Book Description
This paper analyzes a model that features frictions, an operative labor supply margin, and incomplete markets. We first provide analytic solutions to a benchmark model that includes indivisible labor and incomplete markets in the absence of trading frictions. We show that the steady state levels of aggregate hours and aggregate capital stock are identical to those obtained in the economy with employment lotteries, while individual employment and asset dynamics can be different. Second, we introduce labor market frictions to the benchmark model. We find that the effect of the frictions on the response of aggregate hours to a permanent tax change is highly non-linear. We also find that there is considerable scope for substitution between "voluntary" and "frictional" nonemployment in some situations.

Book Description
This paper extends the benchmark New-Keynesian model with a representative agent and rational expectations by introducing two key frictions: (1) agent heterogeneity with incomplete markets, uninsurable idiosyncratic risk, and occasionally-binding borrowing constraints; and (2) bounded rationality in the form of level-k thinking. Compared to the benchmark model, we show that the interaction of these two frictions leads to a powerful mitigation of the effects of monetary policy, which is much more pronounced at long horizons, and offers a potential rationalization of the "forward guidance puzzle". Each of these frictions, in isolation, would lead to no or much smaller departures from the benchmark model. We conclude that the interaction of bounded rationality and market frictions improves the ability of the model to account for the effects of monetary policy.

Book Description
This paper examines the effects of changes in uncertainty of household income on the macroeconomy. Households face substantial idiosyncratic income risk that is up to two orders of magnitude larger than total factor productivity uncertainty, very persistent and varies substantially over the business cycle. We build a New Keynesian model with heterogeneous agents, where changes in precautionary savings due to time-varying uncertainty depress aggregate activity. With countercyclical markups through sticky prices, increased precautionary savings lower aggregate demand and generate significant output losses as the economy is demand-driven in the short-run. The decline in output is more severe, if the central bank is constrained by the zero lower bound. Our results imply that household income uncertainty may be an important factor in explaining the persistent decline of consumption during the Great Recession.

Book Description
An introduction to economic applications of the theory of continuous-time finance that strikes a balance between mathematical rigor and economic interpretation of financial market regularities. This book introduces the economic applications of the theory of continuous-time finance, with the goal of enabling the construction of realistic models, particularly those involving incomplete markets. Indeed, most recent applications of continuous-time finance aim to capture the imperfections and dysfunctions of financial markets—characteristics that became especially apparent during the market turmoil that started in 2008. The book begins by using discrete time to illustrate the basic mechanisms and introduce such notions as completeness, redundant pricing, and no arbitrage. It develops the continuous-time analog of those mechanisms and introduces the powerful tools of stochastic calculus. Going beyond other textbooks, the book then focuses on the study of markets in which some form of incompleteness, volatility, heterogeneity, friction, or behavioral subtlety arises. After presenting solutions methods for control problems and related partial differential equations, the text examines portfolio optimization and equilibrium in incomplete markets, interest rate and fixed-income modeling, and stochastic volatility. Finally, it presents models where investors form different beliefs or suffer frictions, form habits, or have recursive utilities, studying the effects not only on optimal portfolio choices but also on equilibrium, or the price of primitive securities. The book strikes a balance between mathematical rigor and the need for economic interpretation of financial market regularities, although with an emphasis on the latter.
