In a matching model of the labour market in which employers and job seekers have to engage in a costly serach process to create a match, we show that on-the-job search ceteris paribus reduces the unemployment outflow rate. We derive this result for two alternative assumptions as to the relative...

The paper illustrates how, if individual households face random daily demand for the goods they use, a two bin inventory strategy, for determining the frequency of shopping and the amounts purchased, will lead to multi-store shopping and realistic distributions of inter shopping times. This...

This paper links real investment policy to corporate risk management, endogenizing the costs of external financing. Previous literature finds investment efficiency linked to full hedging. In this model, a firm with proprietary information when deciding its investment in a valuable project, may...

This paper is concerned with the Bayesian estimation of non-linear stochastic differential equations when only discrete observations are available. The estimation is carried out using a tuned MCMC method, in particular a blocked Metropolis-Hastings algorithm, by introducing auxiliary points and...

This paper is concerned with the estimation of stochastic differential equations when only discrete observations are available. It primarily focuses on deriving a closed form solution for the one-step ahead conditional transition density using the Milstein scheme. This higher order Taylor...

A temporary-equilibrium model replicating institutional features of low-income agricultural economies is developed. In this model, food is held as an asset; because food production is relatively volatile, those with negative temporary income are net buyers of food. When food is the only asset,...
