In spite of elaborate descriptive and correlational studies, the most ubiquitous phenomenon in economics, namely inflation, has remained unexplained in terms of its mathematical origins. Keynes had attempted to relate inflation to a mechanism of "sticky wages and prices". Hitherto, such theories...

Most prices and interest rates display fluctuating levels that embody extractable energy and equivalent amounts of money. Such fluctuations are also associated with varying degrees of uncertainty. Shannon's derivations of spectral entropy and information content offer computational techniques...

This paper extends the standard Real Business Cycle model to incorporate sectoral shifts in unemployment. Using relative sectoral technology and sectoral tastes shocks, combined with labor adjustment costs across sectors, we assess the possibility of generating persistent aggregate unemployment....

Market clearing is the central issue in macroeconomics. Two centuries of debate on Say’s Law indicates that the issue is not yet settled. This essay proposes that double coincidence is a necessary condition for market clearing, in addition to the equality of demand and supply at equilibrium...

I investigate the effects of the Tax Reform Act of 1986 on the U.S. wealth distribution in a model in which heterogeneous agents face idiosyncratic labor income risk and hold only one asset. The model's stochastic process for earnings is consistent with estimates from panel data. I calibrate the...

An analytical innovation enhances microeconomics, enabling it to answer all questions of macroeconomics. It combines the production and consumption decisions of the individual in one model. For each individual, it identifies the customers of what he sells, and the suppliers of what he buys. It...

This paper studies the effects of different levels of social insurance on efficiency and distribution of resources in a general equilibrium model of a closed economy with heterogeneous agents and moral hazard. I compare optimal allocations of capital, labor supply, and consumption in stationary...

In this paper we establish a link between the volatility of oil price shocks and a positive expected value of inflation in equilibrium (inflation premium). In doing so, we implement the perturbation method to solve up to second order a benchmark New Keynesian model with oil price shocks. In...

This paper presents a sequential model suited to analyze transitions between equilibria. Disequilibrium dynamics are obtained from a standard monopolistic competition model, by introducing a sequential structure and reasonable hypotheses about technology, finance constraints, expectation...

This paper studies the effects of local interactions on the distribution of employment in a Keynesian-type model with strategic complementarities. It is shown that rational expectations generate symmetric equilibria for any interaction structure except autarky. Under adaptive expectations, the...
