Using techniques from deep learning, we show that neural networks can be trained successfully to replicate the modified payoff functions that were first derived in the context of partial hedging by Föllmer and Leukert. Not only does this approach better accommodate the realistic setting of...

We analyze the integration of intermittent renewables-based technologies into an elec- tricity mix comprising of conventional energy. Intermittency is modeled by a contingent electricity market and we introduce demand-side flexibility through the retailing structure. Retailers propose...

We present a general pricing framework applicable in the context of funding and credit risks, with a wide class of underlying jump-diffusion processes, and an extension to this framework for dealing with a particular type of incompleteness. When applied to the special case of incompleteness due...

The objective pursued in the present work is the identification of possible anomalies associated with daily seasonality in the returns of British companies listed on the London Stock Exchange. For this purpose, we examine the profitability of these companies for a the sample period between the...

We investigate the effect of intermediary frictions on asset pricing by examining the role of intermediaries in the convertible bond market. Buy-and-hedge intermediaries distribute new convertible issues but face costs in doing so. We demonstrate that these costs affect the price of...

In intermediated markets, trading takes time and intermediaries extract rents. We estimate a structural search-and-bargaining model to quantify these trading delays, intermediaries’ ability to extract rents, and the resulting welfare losses in government and corporate bond markets. Using...

The difference in unemployment rates between the U.S. and Europe is well documented. In this paper, we develop a model with frictional labor, goods and credit markets to understand how differences in unemployment rates across the U.S. and Europe can be explained by differences in income tax...

In this paper we explore efficiency and optimal policy in decentralized transportation markets that suffer from search frictions, such as taxicabs, trucks and bulk shipping. We illustrate the impact of two externalities: the well-known thin/thick market externalities and what we call pooling...

Macroeconomics is evolving from the study of aggregate dynamics to the study of the dynamics of the entire equilibrium distribution of allocations across individual economic actors. This article reviews the quantitative macroeconomic literature that focuses on household heterogeneity, with a...

Labor market institutions, via their effect on the wage structure, affect the investment decisions of firms in labor markets with frictions. This observation helps explain rising wage inequality in the US, but a relatively stable wage structure in Europe in the 1980s. These different trends are...

The primary aim of this study is to analyze the impact of imperfections in capital markets on individuals' lifetime allocation plans and the resulting implications for income distribution. The model builds upon Samuelson's overlapping generation model with human capital and bequest motives...

Several structural results for the set of competitive equilibria in trading networks with frictions are established: The lattice theorem, the rural hospitals theorem, the existence of side-optimal equilibria, and a group-incentive-compatibility result hold with imperfectly transferable utility...

In intermediated markets, trading takes time and intermediaries extract rents. We estimate a structural search‑and‑bargaining model to quantify these trading delays, intermediaries’ ability to extract rents, and the resulting welfare losses in government and corporate bond markets. Using...

Global and local methods are widely used in international macroeconomics to analyze incomplete-markets models. We study solutions for an endowment economy, an RBC model and a Sudden Stops model with an occasionally binding credit constraint. First-order, second-order, risky steady state and...

We solve a general equilibrium model of an incomplete market with heterogeneous preferences, identifying first-order and second-order effects. Several long-lived agents with different absolute risk-aversion and discount rates make consumption and investment decisions, borrowing from and lending...

In the Covid-19 crisis, most OECD countries have used short-time work (subsidized working time reductions) to preserve employment relationships. This paper studies whether short-time work can save jobs through stabilizing aggregate demand in recessions. First, we show that the consumption risk...

In this paper, we document that households’ consumption expenditures depend on their expected earnings - even after controlling for realized earnings and wealth. To explain this evidence, we develop and structurally estimate a standard-incomplete markets model in which rational households...

This paper develops a simulation-based solution method to solve large state space macrofinance models using machine learning. We use a neural network (NN) to approximate the expectations in the optimality conditions in the spirit of the stochastic parameterized expectations algorithm (PEA)....

In this paper, we document that households' consumption expenditures depend on their expected earnings - even after controlling for realized earnings and wealth. To explain this evidence, we develop and structurally estimate a standard-incomplete markets model in which rational households...

We investigate whether US households possess advance information about their future income and what this means for consumption insurance. Based on insights from a theoretical model, we propose a new test to detect advance information, which requires only panel data on consumption and income....

This paper examines how collective bargaining through unions and workplace codetermination through works councils shape labour market imperfections and how labour market imperfections matter for employer wage premia. Based on representative German plant data for the years 1999–2016, we...

This paper follows an incomplete market pricing approach to analyze the evaluation of weather derivatives and the viability of a weather derivatives market in terms of hedging. A utility indifference method is developed for the specification of indifference prices for the seller and buyer of a...

Using survey data, we document that predictable exchange rate forecast errors are responsible for the uncovered-interest-parity (UIP) puzzle and its reversal at longer horizons. We develop a general-equilibrium model based on shock misperception and over-extrapolative beliefs that reconciles...

International outsourcing to lower cost countries such as China and India can best be understood through the enrichment of trade models to include concepts from industrial organization and contract theory that explain the vertical organization of production. The combination of trade with the...

This paper reviews the theoretical functions, history, and policy problems raised by the international capital market. The goal is to offer a perspective on both the considerable advantages the market offers and on the genuine hazards it poses, as well as on the avenues through which it...

This chapter studies how incomplete information helps accommodate frictions in coordination, leading to novel insights on the joint determination of expectations and macroeconomic outcomes. We review and synthesize recent work on global games, beauty contests, and their applications. We...

In this paper, we survey non-competitive theories of training. With competitive labor markets, firms never pay for investments in general training, whereas when labor markets are imperfect, firm-sponsored training arises as an equilibrium phenomenon. We discuss a variety of evidence which...

We introduce convenience yields on dollar bonds into an incomplete-market equilibrium model of exchange rates and interest rates. The convenience yield enters as a stochastic wedge in the Euler equation for exchange rate determination. The model identifies a novel safe-asset convenience yield...

During recessions, output prices tend to rise relative to wages and raw-materials prices. One explanation of this fact is that imperfectly competitive firms compete less aggressively during recessions - that is, markups of price over marginal cost are countercyclical. We present a model in which...

This study investigates the effects of embodied technological progress on unemployment using a search-matching model with heterogeneous multiworker firms. New technology creates two firm types: those that become obsolete and those that reap the technological rewards. I develop a model in which...

This paper examines the impact of financial market imperfections on long-term productivity growth. It focuses on failures in markets for the sale of equity securities and hence on the failure of markets which help firms diversify the risks of real investment. The paper examines separately...

We develop an equilibrium model of industrial structure in which the organization of firms is endogenous. Differentiated consumer products can be produced either by vertically integrated firms or by pairs of specialized companies. Production of each variety of consumer good requires a unique,...

We argue that the incomplete information which the government has about domestic agents means that tariffs become an optimal instrument to protect them from import competition. We solve for the optimal government policies. subject to the political constraint of ensuring Pareto gains from trade,...

The impact of transaction costs on asset pricing in equilibrium is rarely studied. We study an equilibrium model with proportional transaction costs where two investors trade in a derivative to hedge non-traded endowments. For any positive transaction cost there always exist no trade equilibria....

In the presence of informational frictions, bond markets aggregate the private information of firms and intermediaries, and bond prices serve as signals about the financial sector and the real economy. Such frictions amplify the credit constraints faced by intermediaries, depressing firm...

This paper proposes a spatial model of imperfect competition in markets with selection to investigate whether imperfect competition exacerbates or offsets inefficiencies caused by selection. We find that no degree of imperfect competition achieves the first-best efficient allocation. This holds...

This paper presents a simple but quite general framework for analyzing the impact of informational externalities. By identifying the traditional pecuniary effect of these externalities which nets out,the paper greatly simplifies the problem of determining when tax interventions can be Pareto...
