摘要：This paper considers the political credibility of allocations in settings with dynamic private information. It embeds a benchmark dynamic moral environment into political economy games which feature repeated voting over mechanisms. Optimal politically credible allocations are shown to solve virtual planning problems with social discount factors in excess of the private one. (C) 2007 Elsevier B.V. All rights reserved.

摘要：A recent literature has merged the New Keynesian and the search and matching frameworks, which has allowed the former to analyze the joint dynamics of unemployment and inflation. This paper analyzes optimal monetary policy in this kind of hybrid framework. I show that zero inflation is optimal when all wages are Nash bargained in every period and the economy's steady state is efficient. In the more realistic case in which nominal wage bargaining is staggered, a case against price stability ari...

摘要：We analyze the effect of the projected demographic transition on the political support for social security, and equilibrium outcomes. Embedding a probabilistic-voting setup of electoral competition in the standard OLG model with capital accumulation, we find that intergenerational transfers arise in the absence of altruism, commitment, or trigger strategies. Closed-form solutions predict population ageing to lead to higher social security tax rates, a rising share of pensions in GDP, but event...

摘要：Based partially on the belief that innovation is not possible under perfect competition, a huge number of papers have been written about the nature of innovation under monopoly or oligopoly. In fact, competitive rents can and do sustain innovation in the complete absence of monopoly power. However, little is known about the source and significance of these rents, or about the way in which innovative activity takes place under conditions of competition. We begin to remedy this imbalance by exam...

摘要：Using a model with constant relative risk-aversion preferences, endogenous labor supply and partial insurance against idiosyncratic wage risk, this paper provides an analytical characterization of three welfare effects: (a) the welfare effect of a rise in wage dispersion, (b) the welfare gain from completing markets, and (c) the welfare effect from eliminating risk. The analysis reveals an important trade-off for these welfare calculations. On the one hand, higher wage uncertainty increases th...

摘要：This paper studies the incentives of participants in a real-time gross settlement system with and without the addition of a liquidity-saving mechanism (LSM). Participants in the model face a liquidity shock and different costs for delaying payments. They trade off the cost of delaying a payment against the cost of borrowing liquidity from the central bank. The main contribution of the paper is to show that the design of an LSM has important implications for welfare. In particular, parameters d...

摘要：Costly nominal wage adjustment has received renewed attention in the design of optimal policy. in this paper, we embed costly nominal wage adjustment into the modern theory Of frictional labor markets to Study optimal fiscal and monetary policy. The main result is that the optimal rate of price inflation is quite volatile despite the presence of nominal wage rigidities. This finding contrasts with results obtained in standard sticky-wage models, which employ neoclassical labor markets at their...

摘要：A segmented markets model of monetary policy is constructed, in which a novel feature is goods market segmentation, and its relationship to conventional asset market segmentation. The implications of the model for the response of prices, interest rates, consumption, labor supply, and output to monetary policy are determined. As well, optimal monetary policy is studied, as are the costs of inflation. The model features persistent nonneutralities of money, relative price effects of increases in ...

摘要：Early studies of business cycles argued that contractions in economic activity were briefer (shorter) and more violent (rapid) than expansions. This paper systematically investigates this claim and in the process discovers a robust new business cycle fact: contractions in employment are briefer and more violent than expansions but we cannot reject the null of equal brevity and violence for expansions and contractions in output. The difference arises because employment typically lags output aro...

摘要：An incomplete-market life-cycle model with indivisible labor makes career lengths and human capital accumulation respond to labor tax rates and government supplied non-employment benefits. We compare aggregate and individual outcomes in this individualistic incomplete-market model with those in a comparable collectivist representative-family model with employment lotteries and complete-insurance markets. The incomplete- and complete-market structures assign leisure to different types of indivi...
