We examine the determinants of low income transitions using first-order Markov models that control for initial conditions effects (those found to be poor in the base year may be a non-random sample) and for attrition (panel retention may also be non-random). Our econometric model is a form of...

In this paper R2-type measures of the explanatory power of multivariate linear and categorical probit models proposed in the literature are reviewed and their deficiencies are discussed. It is argued that a measure of the explanatory power should take into account the components which are...

Empirical work on price-cost margins often treats costs as exogenous. Allowing for endogenous costs when estimating price-cost margins is the topic of this paper. Methodologically, the endogenous cost model we propose leads to an additional equation that allows for the simultaneity in price...

This paper investigates the strategic value of the managerial incentive scheme in affecting firms' incentive in R&D investment and their product market activities. Firstly, we find that in Cournot-quantity competition, owners strategically assign a non-profit-maximization objective to their...

This paper shows that stricter enforcement may increase tax evasion. Individuals vote on a linear income tax which is used to finance lump sum transfers. Stricter enforcement may make redistributive taxation more attractive to the decisive voter. The tax rate and transfer may rise which in turn...

A new method for constructing R&D capital stocks is proposed. Following Schumpeter, the development of R&D capital stocks is modelled as a process of creative destruction. Newly generated knowledge is assumed not only to add to the existing R&D capital stocks but also, by displacing old...

Becker and Murphy (1988) constructed, in a well-known paper, a model of rational addiction in which people solve a dynamic optimization problem, choose an optimal timepath of drug consumption and thereby maximize lifetime utility. The model leads to the hypothesis that future consumption is a...

The main objective of this paper is to understand the causes and symptoms of currency crises by reviewing its seminal literature, establishing its determinants, and outlining some of the relevant issues. The paper highlights the need to comprehend the process, which may lead to the inconsistency...

We study the political economy of commuting subsidies in a model of a monocentric city with two income classes. Depending on housing demand and transport costs, either the rich or the poor live in the central city and the other group in the suburbs. Commuting subsidies increase the net income of...
