A person cannot make many decisions at a time, but an organization needs millions of interrelated decisions. We incorporate this idea into a standard theory of production. Two assumptions are emphasized: an agent cannot optimize more than one input at a time, and there is interaction among...

This paper derives the HJB (Hamilton-Jacobi-Bellman) equation for sophisticated agents in a finite horizon dynamic optimization problem with non-constant discounting in a continuous setting, by using a dynamic programming approach. Special attention is paid to the case of free terminal time....

This paper presents a monetary explanation for several business-cycle facts: (i) household and business investment are procyclical, (ii) business investment lags household investment, (iii) household investment is positively correlated with M1, and (iv) household credit outstanding is positively...

Asset location decisions observed in practice deviate substantially from the predictions of theoretical models. This paper develops a life cycle model with a progressive tax system to quantitatively evaluate two explanations of the asset location puzzle. We find that taxes matter significantly...

Options are believed to contain unique information on the risk-neutral moment generating function (MGF) or the risk-neutral probability density function (PDF) of the underlying asset. This paper applies the wavelet method to approximate the implied risk-neutral MGF from option prices. Monte...

Can long-run identified structural vector autoregressions (SVARs) discriminate between competing models in practice? Several authors have suggested SVARs fail partly because they are finite-order approximations to infinite-order processes. We estimate vector autoregressive moving average (VARMA)...

This paper analyzes the macroeconomic implications of real-indexed bonds using a general equilibrium model of a small open economy with financial frictions. Although indexed bonds provide a hedge to income fluctuations and can thereby mitigate the effects of financial frictions, they introduce...

This paper studies the role of the order book market mechanism in shaping price movements and the order flow in a zero-intelligence agent model of a dynamic limit-order market. The results indicate that many stylised facts of limit-order markets are not dependent on individual strategic...

This paper investigates whether the monetary transmission mechanism has changed or whether apparent changes are due to changes in the volatility of exogenous shocks. Also, the question of whether any changes have been gradual or abrupt is considered. A mixture innovation model is used which...

We present a simple behavioral model with chartists and fundamentalists and analyze their trading behavior in both a floating and a target zone exchange rate regime. When applied to the floating regime, the model replicates the well-known stylized facts, such as excess volatility, fat tails,...
