Book Description
This dissertation consists of three essays about heterogeneous agents in the dynamic economy and how to deal with the asymmetric information arose by heterogeneity. Firstly, I consider the optimal taxation issue in a dynamic endogenous growth model with considering human capital accumulation, and agents ability is heterogeneous and private information. Moreover, the agents with higher ability have positive external effects on others. By using the two-sector endogenous model, I show that it is optimal to impose different income and capital income taxes on people with different abilities. Specifically, positive marginal income tax is adopted for people with lower ability while no tax is imposed for people with higher ability; marginal capital income tax is zero whatever the agent's is low or high. As for people using the capital and labor for human capital accumulation, the government should subsidize them whatever their ability is. Secondly, I study the optimal monetary and fiscal policy with heterogeneous agents based on the search-theoretical environment where money is essential and consider the private information. I first solve the households' problem in the centralized and decentralized market, and find out the optimal conditions. Then, in this section, I describe the problem that social planner faces by involving uncertainty and agents whose types are continuous. By comparing the optimal conditions in this generous setting, I show that the Friedman rule is no longer optimal when jointed with nonlinear taxation of income. Moreover, the capital income taxation is not zero. Moreover, I constructs a general theoretical model to consider two kinds of financial frictions in the economy with financial intermediaries. By quantitative analysis the model with three separate shocks which are a negative collateral shock, a negative productivity shock and a positive shock to bankers' divert rate, I find that a negative collateral shock which tightens firms' financing constraints on investment can generate an equity price boom which is different from what is observed in recessions. Therefore, the collateral shock is not the main reason for the business cycle, while the negative productivity shock and bankers' moral hazard problem are more important aspects to explain current economy.

Book Description
This book analyses situations in which individual agents, who might be different from each other, interact and produce behaviour on the aggregate level which does not correspond to that of the average actor. This leads to aggregate outcomes which would be impossible to explain in a more standard approach. Aggregation generates structure and, as a result, interaction and heterogeneity can be handled and we no longer have to rely on the over-simplified reduction of the behaviour of the economy to that of a "rational" individual.

Book Description
Volume 32 of the NBER Macroeconomics Annual features six theoretical and empirical studies of important issues in contemporary macroeconomics, and a keynote address by former IMF chief economist Olivier Blanchard. In one study, SeHyoun Ahn, Greg Kaplan, Benjamin Moll, Thomas Winberry, and Christian Wolf examine the dynamics of consumption expenditures in non-representative-agent macroeconomic models. In another, John Cochrane asks which macro models most naturally explain the post-financial-crisis macroeconomic environment, which is characterized by the co-existence of low and nonvolatile inflation rates, near-zero short-term interest rates, and an explosion in monetary aggregates. Manuel Adelino, Antoinette Schoar, and Felipe Severino examine the causes of the lending boom that precipitated the recent U.S. financial crisis and Great Recession. Steven Durlauf and Ananth Seshadri investigate whether increases in income inequality cause lower levels of economic mobility and opportunity. Charles Manski explores the formation of expectations, considering the efficacy of directly measuring beliefs through surveys as an alternative to making the assumption of rational expectations. In the final research paper, Efraim Benmelech and Nittai Bergman analyze the sharp declines in debt issuance and the evaporation of market liquidity that coincide with most financial crises. Blanchard’s keynote address discusses which distortions are central to understanding short-run macroeconomic fluctuations.

Book Description
"The process by which securities are traded is very different from the idealized picture of a frictionless and self-equilibrating market offered by the typical finance textbook. This book offers a more accurate and authoritative take on this process. The book starts from the assumption that not everyone is present at all times simultaneously on the market, and that participants have quite diverse information about the security's fundamentals. As a result, the order flow is a complex mix of information and noise, and a consensus price only emerges gradually over time as the trading process evolves and the participants interpret the actions of other traders. Thus, a security's actual transaction price may deviate from its fundamental value, as it would be assessed by a fully informed set of investors. The book takes these deviations seriously, and explains why and how they emerge in the trading process and are eventually eliminated. The authors draw on a vast body of theoretical insights and empirical findings on security price formation that have come to form a well-defined field within financial economics known as "market microstructure." Focusing on liquidity and price discovery, the book analyzes the tension between the two, pointing out that when price-relevant information reaches the market through trading pressure rather than through a public announcement, liquidity may suffer. It also confronts many striking phenomena in securities markets and uses the analytical tools and empirical methods of market microstructure to understand them. These include issues such as why liquidity changes over time and differs across securities, why large trades move prices up or down, and why these price changes are subsequently reversed, and why we observe temporary deviations from asset fair values"--

Book Description
This paper examines how country, industry and firm characteristics interact in general equilibrium to determine nations' responses to trade liberalization. When firms possess heterogeneous productivity, countries differ in relative factor abundance and industries vary in factor intensity, falling trade costs induce reallocations of resources both within and across industries and countries. These reallocations generate substantial job turnover in all sectors, spur relatively more creative destruction in comparative advantage industries than comparative disadvantage industries, and magnify ex ante comparative advantage to create additional welfare gains from trade. The relative ascendance of high-productivity firms within industries boosts aggregate productivity and drives down consumer prices. In contrast with the neoclassical model, these price declines dampen and can even reverse the real wage losses of scarce factors as countries liberalize.

Book Description
The 2008 financial crisis, the rise of Trumpism and the other populist movements which have followed in their wake have grown out of the frustrations of those hurt by the economic policies advocated by conventional economists for generations. Despite this, textbooks continue to praise conventional policies such as deregulation and hyperglobalization. This textbook demonstrates how misleading it can be to apply oversimplified models of perfect competition to the real world. The math works well on college blackboards but not so well on the Main Streets of America. This volume explores the realities of oligopolies, the real impact of the minimum wage, the double-edged sword of free trade, and other ways in which powerful institutions cause distortions in the mainstream models. Bringing together the work of key scholars, such as Kahneman, Minsky, and Schumpeter, this book demonstrates how we should take into account the inefficiencies that arise due to asymmetric information, mental biases, unequal distribution of wealth and power, and the manipulation of demand. This textbook offers students a valuable introductory text with insights into the workings of real markets not just imaginary ones formulated by blackboard economists. A must-have for students studying the principles of economics as well as micro- and macroeconomics, this textbook redresses the existing imbalance in economic teaching. Instead of clinging to an ideology that only enriched the 1%, Komlos sketches the outline of a capitalism with a human face, an economy in which people live contented lives with dignity instead of focusing on GNP.
