This paper investigates whether insiders use private information in their decision to exercise executive stock options. Consistent with existing research, exercises overall do not yield subsequent abnormal returns. Categorising exercises by the proportion of stock sold at exercise yields a...

Within the context of an agent-based model, model selection by the economic agents is introduced and investigated. To achieve this, a specific agent, the “economic research instituteâ€, is set up and produces regular forecasts of the economy which are published to the economic agents....

A dynamic Tobit model with Time-varying parameters is proposed for the daily reaction function of the Open Market Desk of the US Federal Reserve. Such a model offers a more realistic depiction of the Desk's behavior than those of past contributions in the literature as it allows for both...

We propose the use of a classical tool in PDE theory, the parametrix method, to build approximate solutions to generic parabolic models for pricing and hedging contingent claims. We obtain an expansion for the price of an option using as starting point the classical Black and Scholes formula....

We investigate possible determinants of the increase of household debt and smaller consumption fluctuations since the 1980s in the US. We use a heterogeneous-agent model, in which labor income is risky and markets are incomplete. Consumers use durables not only as collateral for their debt but...

We connect two major strands of the recent monetary policy literature, i) the search for well microfounded optimising models consistent with macroeconomic data, especially persistence in inflation, and ii) the wealth of newly available microeconomic data on price changing behaviour from the...

This paper studies the implications of labor taxation in determining the sensitivity of an economy to macroeconomic shocks. We construct a New Keynesian business cycle model with matching frictions of the labor market, where sluggish employment adjustment implies a key role for labor markets in...

This paper investigates the implications of the addition of differential population dynamics to a simple 2x2x2 model of international trade within an overlapping-generations (OLG) framework, by assuming that one of the trading partners has the power to set the terms of trade (i.e., is large) at...

In this paper, we investigate the behavior of the exchange rate within the framework of an asset pricing model. We assume boundedly rational agents who use simple rules to forecast the future exchange rate. They test these rules continuously using two learning mechanisms. The first one, the...

This paper re-considers the empirical relevance of the Lucas critique using a sticky price model in which a weak central bank response to inflation generates equilibrium indeterminacy. The model is calibrated on the magnitude of the historical shift in the Fed's policy rule and is capable of...
