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....

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...

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...

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...

We consider linear dynamic models with rational expectations in case of incomplete and asymmetric information as well as agents heterogeneity. This problem requires solving infinite dimensional matrix equations. We propose asymptotic expansion method to reduce this problem to the finite...

Can factor accumulation still help us understand differences in capital inflows and income across countries? This paper offers a quantitative evaluation of neoclassical models of growth with collateral constraints. Previous work has found evidence that supports the qualitative predictions of...

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...
