Abstract Chapter 1. Heterogeneous Entrepreneurial Ability and Wealth Inequality Models with entrepreneurship can reproduce high wealth concentration at the top. The key assumption is the borrowing constraint, that is, households are unable to borrow enough assets to start a business or invest optimally in the business. However, some empirical evidences show that borrowing constraint does not matter for the majority of households in the US. This paper seeks to generate high wealth concentration at the top without assuming borrowing constraint. The baseline model that introduces heterogeneity in entrepreneurial ability is able to match the wealth distribution while the model assuming same entrepreneurial ability fails. Besides wealth distribution, the baseline model generates other moments that are consistent with the data. Chapter 2. Taxing Top Earners: The Role of Entrepreneurs This paper studies the optimal top marginal income tax rate in a quantitative framework with entrepreneurial choice, financing constraints, and realistic earnings and wealth distributions. I find that the revenue-maximizing top tax rate is approximately 41 percent -- close to the recent levels in the US. In contrast, when calibrated with only workers to match realistic earnings and wealth distributions, the model predicts a revenue-maximizing top tax rate of 81 percent -- close to the established view. There are two channels through which the baseline model has a lower revenue-maximizing top tax rate. First, the wealth distribution channel: increasing the top tax rate decreases wealth accumulation and leads to a less skewed wealth distribution in the long run (there are more top entrepreneurs with low wealth and less top entrepreneurs with high wealth). With financing constraints, there is a similar change in the business earnings distribution, implying a fall in the average business earnings at the top. Second, the general equilibrium effect on labor earnings of workers: in the model with entrepreneurs, increasing the top tax rate reduces the capital stock much more than labor supply, which decreases the capital-labor ratio and thus the equilibrium wage rate in the model economy. Finally, I find that the welfare-maximizing top marginal income tax rate is close to the revenue-maximizing one. Chapter 3. Household Heterogeneity and Consumption Amplification Macroeconomic models with household heterogeneity in wealth can generate larger consumption response to aggregate shocks compared to a representative-agent economy. In other words, there is consumption amplification associated with wealth heterogeneity. However, I find that in a Krusell-Smith type real business cycle (RBC) model, this amplification effect is only significant at the onset of a recession and gradually dies out as the recession proceeds. The finding is of interest because part of the motivation for the widely adoption of models with wealth heterogeneity is their different and empirically plausible implications for consumption dynamics compared with representative-agent models. I then introduce household heterogeneity in housing and find that the model with housing has more persistent amplification effect on consumption during the recession.

This thesis is composed of three independent chapters, but all centered around the broader topic of how macroeconomic policies interact with various aspects of household heterogeneity. Monetary Policy and Inequality under Labor Market Frictions and Capital-Skill Complementarity We provide a new channel through which monetary policy has distributional consequences at business cycle frequencies. We show that an unexpected monetary easing increases labor income inequality between high and less-skilled workers. In particular, this effect is prominent in sectors intensive in less-skilled labor, that exhibit high degree of capital-skill complementarity (CSC) and are subject to matching inefficiencies. To rationalize these findings we build a New Keynesian DSGE model with asymmetric search and matching (SAM) frictions across the two types of workers and CSC in the production function. We show that CSC on its own introduces a dynamic demand amplification mechanism: the increase in high-skilled employment after a monetary expansion makes complementary capital more productive, encouraging a further rise in investment demand and creating a multiplier effect. SAM asymmetries magnify this channel. Monetary-Fiscal Interactions and Redistribution in Small Open Economies Ballooning public debts in the wake of the covid-19 pandemic can present monetary-fiscal policies with a dilemma if and when neutral real interest rates rise, which might arrive sooner in emerging markets: policymakers can stabilize debts either by relying on fiscal adjustments (AM-PF) or by tolerating higher inflation (PM-AF). The choice between these policy mixes affects the efficacy of the fiscal expansion already today and can interact with the distributive properties of the stimulus across heterogeneous households. To study this, I build a two agent New Keynesian (TANK) small open economy model with monetary-fiscal interactions. Targeting fiscal transfers more towards high-MPC agents increases the output multiplier of a fiscal stimulus, while raising the degree of deficitfinancing for these transfers also helps. However, precise targeting is much more important under the AM-PF regime than the question of financing, while the opposite is the case with a PM-AF policy mix: then deficit-spending is crucial for the size of the multiplier, and targeting matters less. Under the PM-AF regime fiscal stimulus entails a real exchange rate depreciation which might offset "import leakage" by stimulating net exports, if the share of hand-to-mouth households is low and trade is price elastic enough. Therefore, a PM-AF policy mix might break the Mundell-Fleming prediction that open economies have smaller fiscal multipliers relative to closed economies. Weak Wage Recovery and Precautionary Motives after a Credit Crunch During the economic recovery following the financial crisis many advanced economies saw subdued wage dynamics, in spite of falling unemployment and an increasingly tight labour market. We propose a mechanism which can account for this puzzle and work against usual aggregate demand channels. In a heterogeneous agent model with incomplete markets we endogenize uninsurable idiosyncratic risk through search-and-matching (SAM) frictions in the labour market. In this setting, apart from the usual precautionary saving behaviour, households can self-insure also by settling for lower wages in order to secure a job and thereby avoid becoming borrowing constrained. This channel is especially pronounced for asset-poor agents, already close to the constraint. We introduce a credit crunch into this framework modelled as a gradual tightening of the borrowing constraint (and utilizing a continuous time approach, known as HACT). The perfect foresight transition dynamics feature falling wages despite a tightening labour market and expanding employment. As households suddenly find themselves closer to the borrowing constraint, the increased precautionary motive drives them to accept lower wages in the bargaining process, while firms respond to this by posting more vacancies, leading to a tighter labour market and falling unemployment. If the household deleveraging pressure is persistent enough after the credit crunch, it can explain the weak wage recovery in spite of already stronger aggregate demand.

This thesis contains four independent essays studying the consequences of household heterogeneity for Macroeconomics. The first chapter studies the implications of household heterogeneity for equilibrium prices. I break with the canonical assumptions of homothetic preferences and the law of one price to show how heterogeneity in consumption baskets and search for price bargains affects posted prices. Analytical results from search theory and empirical evidence from big data on households' grocery transactions show that price distributions respond to the composition of buyers. In a quantitative heterogeneous agent model with endogenous price dispersion for multiple varieties, I find that the response of retailers to households' search effort is quantitatively important to differentiate between inequality in expenditure and consumption. It more than doubles the direct effect of paying more or less given posted prices, which has been the focus of previous literature. Furthermore, I find that household heterogeneity helps to account for the empirical cyclicality of retail prices and markups in response to aggregate shocks, and has implications for the response of prices to redistributive policies. In the second chapter, which is joint work with Annika Bacher and Philipp Grübener, we show how households with two members can insure themselves against the job loss of a primary earner through the labor force entry of a nonparticipating spouse. We document empirically that this margin is predominantly used by young households. In a two-member life cycle model with endogenous arrival rates, human capital accumulation, and extensive-margin labor supply, we explore how differences in labor market opportunities and asset holdings contribute to this pattern. Our findings suggest that the age difference is predominantly explained by better insurance through asset holdings for the old, while differences in arrival rates and human capital play a smaller role. In the third chapter, which is joint work with Caterina Mendicino and Marcel Peruffo, we study differences in the exposure to bank distress along the income distribution. We develop a two-asset heterogeneous agent model with a financial sector and use this framework to show that banking sector losses disproportionately harm low-income households while rich households adjust their savings behavior to profit from fluctuations in asset prices. This is why welfare losses from bank distress are considerably more dispersed than consumption responses. We find the model-implied consumption responses to be in line with empirical evidence on the relationship between bank equity returns and consumption across households. In the forth chapter, I study how wealth holdings can affect households' incentives to form precise expectations about future inflation rates. I document empirically how the dispersion of expectations changes along the wealth distribution and develop a consumption-savings model with costly expectation formation to study implications for the effectiveness of forward guidance policies. I show endogenous expectation formation to significantly lower the effectiveness of forward guidance policies due to selection in which households are paying attention to news about inflation.

"Chapter 1 develops a heterogeneous-agent general equilibrium model that incorporates both intensive and extensive margins of labor supply. A nonconvexity in the mapping between time devoted to work and labor services distinguishes between extensive and intensive margins. We consider calibrated versions of this model that differ in the value of a key preference parameter for labor supply and the extent of heterogeneity. The model is able to capture the key features of the empirical hours worked distribution, including how individuals transit within this distribution. We then study how the various specifications influence labor supply responses to temporary shocks and permanent tax changes, with a particular focus on the intensive and extensive margin elasticities in response to these changes. We find important interactions between heterogeneity and the extent of curvature in preferences. Chapter 2 builds a model of family labor supply in which individuals choose between full-time work, part-time work, and nonemployment. The model is calibrated to replicate the movements of both male and female workers among these states. The willingness to substitute hours over time (the so-called intertemporal elasticity of labor supply) is critical for many economic analysis. A common strategy for uncovering the value of this willingness is to carry out structural estimation on micro panel data. One general issue in this estimation exercises using micro data is that misspecification of the constraints that individuals face is likely to influence inference about preference parameters. In the model economy, although the individual labor supply problem is a discrete choice problem, individuals are able to adjust hours along the intensive margin by moving between part-time and fulltime work. Intuitively, adjustment along the intensive margin potentially allows one to estimate the true value of the underlying curvature parameter describing the utility from leisure. We explore the extent to which standard labor supply methods can achieve this in our setting. Although these methods deliver precise estimates that are significantly different from zero, the estimates are effectively unrelated to the true underlying values. These methods also deliver elasticity estimates for women, even when the underlying preference parameters are the same for men and women. Chapter 3 investigates the optimal progressive tax code in an incomplete-market economy in which households are linked intergenerationally by altruism and earning ability. The model economy is calibrated to that of the US with the progressive tax code suggested by Gouviea and Strauss (1994). First, I compute the equilibrium with the optimal progressive tax code. Second, I investigate the extent to which the size of government welfare programs affects the optimal progressivity of the income tax code. I find that the optimal tax code for an economy populated with altruistic households is approximately equivalent to a proportional tax of 23.1% with a fixed deduction of approximately $17,000 in 1990 US dollars. For an economy populated with non-altruistic households, however, these numbers are 18.8% and $12,000 respectively. This result implies that inequality is more severe in an economy with intergenerational links so that the policy maker requires a more progressive tax system to provide insurance. Additionally, I find that when the size of the government welfare program is chosen carefully, the additional insurance benefits from the progressive income tax code disappear"--Pages iv-v.

This dissertation studies macroeconomics with regional heterogeneity in three general dimensions. First, it documents some novel empirical patterns of regional heterogeneity (in Chapter 1, 2, 3). Second, these empirical facts are used to identify key economic forces underlying theoretical models (in Chapter 1 and 3). Third, aggregate implications of regional heterogeneity are also studied (in Chapter 1). In the first chapter of this dissertation, I highlight time-varying regional risk and federal fiscal transfer policy as two competing forces driving regional risk sharing over the business cycle and in turn quantify their impacts on aggregate fluctuations. I find that during an economic downturn, increased regional risk worsens risk sharing and amplifies the impact of aggregate productivity shocks. However, state-contingent federal government transfers provide additional risk sharing and help stabilize the aggregate economy, by providing insurance to the regions that need it the most. In the second chapter (joint with Noah Williams), we first estimate a quarterly dataset for state-level aggregates by building a novel empirical framework that allows for mixed-frequency raw data with measurement errors. We then apply this dataset to study the monetary policy effects at the state levels. We find that states behave remarkably homogeneous with each other in their responses of output and price to an unanticipated monetary policy shock. In the third chapter (joint with Noah Williams), we use the state-level quarterly dataset to analyze the impact of unexpected changes in federal personal and corporate income taxes. We find substantial heterogeneity in the impact of federal fiscal policy across states, with more than half having no significant response to the tax cuts. In addition, less capital-intensive states have larger responses to corporate tax cuts. Although puzzling in standard models, a model with corporate and non-corporate sectors is consistent with this evidence. Overall, our results suggest the importance of variation and reallocation across states in evaluating federal policy.

This dissertation consists of two chapters that explore how micro-level heterogeneity helps us understand the dynamics of macroeconomic variables. Chapter 2 shows that the evolving likelihood of marriage and divorce is an essential factor in accounting for the changes in housing decisions over time in the United States. I build and estimate a life-cycle model of single and married households who face exogenous age-dependent marital transition shocks and then conduct a decomposition analysis between 1970 and 1995. The results show that household formation shocks could account for about 30% of the increase in the single's homeownership rate and play a crucial role in generating the observed sign of change in portfolio share of married households. The extended analysis on recent years after 1995 shows that the continuing decrease in marriage prospects contributed to push up the single's homeownership rate during the housing boom in the mid 2000s. Chapter 3 develops a state-space model with a state-transition equation that takes the form of a functional vector autoregression and stacks macroeconomic aggregates and a cross-sectional density. The measurement equation captures the error in estimating log densities from repeated cross-sectional samples. The log densities and the transition kernels in the law of motion of the states are approximated by sieves, which leads to a finite-dimensional representation in terms of macroeconomic aggregates and sieve coefficents. We illustrate how the model works based on the simulation of the Krusell-Smith economy and conduct an empirical analysis on the joint dynamics of technology shocks, per capita GDP, employment rates, and the earnings distribution.

The goal of this chapter is to study how, and by how much, household income, wealth, and preference heterogeneity amplify and propagate a macroeconomic shock. We focus on the U.S. Great Recession of 2007-2009 and proceed in two steps. First, using data from the Panel Study of Income Dynamics, we document the patterns of household income, consumption and wealth inequality before and during the Great Recession. We then investigate how households in different segments of the wealth distribution were affected by income declines, and how they changed their expenditures differentially during the aggregate downturn. Motivated by this evidence, we study several variants of a standard heterogeneous household model with aggregate shocks and an endogenous cross-sectional wealth distribution. Our key finding is that wealth inequality can significantly amplify the impact of an aggregate shock, and it does so if the distribution features a sufficiently large fraction of households with very little net worth that sharply increase their saving (i.e. they are not hand-to mouth) as the recession hits. We document that both these features are observed in the PSID. We also investigate the role that social insurance policies, such as unemployment insurance, play in shaping the cross-sectional income and wealth distribution, and through it, the dynamics of business cycles.

The first chapter of the thesis is entitled A Brief History of Land Value Taxation in Economic Theory. The issue of land rents and their taxation through a land value tax (LVT) was as a hotly debated topic in economic theory since classical age and until the early twentieth century, when it mostly vanished as a research subject. I provide a brief history of the evolution of the concept of land value taxation in economic theory in order to understand the reasons why it fell out of favor as a research subject in the literature. I identify this outcome as being a consequence of developments both inside and outside academia. The second chapter is entitled Tax Housing or Land? Distributional Effects of Property Taxation in Germany. Despite its theoretical merits, Land Value Taxation is not a common policy instrument. One of the main reasons is uncertainty regarding its distributional impacts. Using a general equilibrium model with heterogeneous agents calibrated to an unique household level dataset of German homeowners in 2017, we assess the distributional effects of replacing a housing tax with a LVT. Our data shows the share of land value in property value is 33%, on average, with considerable household heterogeneity, both within and across regions, and within income levels. We add to the empirical literature by showing land values are more concentrated than property values, but, within regions, not as strongly correlated with income, making it less progressive than a standard property tax for homeowners. Our model is the first to allow for an efficiency-equity trade-off from the introduction of a revenue neutral LVT. Results from the model show the introduction of a LVT increases residential investment substantially, reducing housing rents and benefiting renters. It also leads to migration from urban regions, promoting regional convergence. Landowners with high land holdings lose, in general, but most other landowners across income levels benefit, especially in non-urban regions. Overall, introduction of a LVT increases welfare, despite a minor regressive tendency in urban regions for homeowners. The third chapter is entitled Credit Spirals: Spillovers between Firm and Household Borrowing in a Small Open Economy. The paper deals with an open economy model of financial crisis with sudden stops, but featuring both household and firm borrowing. So far, the literature has mostly ignored the effects of joint borrowing for financial stability. The model features occasionally binding borrowing constraints and shows how borrowing decisions in one sector can reinforce standard capital flows and increase the volatility of collateral asset through strategic complementarities, beyond what standard financial accelerator models would predict. These spillovers can lead to sharper reductions in borrowing and consumption during sudden stop events.
