Abstract We study models of the formation of citation networks in a setting where authors/firms care about their citations and are rational. The effect of these two features on the diffusion of useful ideas in a setting with complete information about past citations leads to multiplicity of...

Productivity bias hypothesis claims that deviation of the PPP based exchange rate from the equilibrium rate is mainly due to productivity differentials among countries. Early studies that employed cross‐sectional data in testing the hypothesis provided mixed results. A few time‐series...

This paper considers the distributional dynamics of a well‐known corruption index. Specifically, we are interested in evaluating whether corruption is best characterized as multimodal (i.e. pointing to clusters of countries with persistently different levels of corruption) and whether there...

Purpose – The purpose of this paper is to analyze the effect of utility and production externalities on the equilibrium efficiency, and to devise tax policies capable of correcting the distortions caused by the external effects. Design/methodology/approach – The paper analyzes a...

Purpose – The purpose of this paper is to develop a model of international capital market equilibrium where investors exhibit home‐country bias due to their desire to hedge real consumption. Design/methodology/approach – This paper posits a two‐stage process of portfolio choice for the...

Purpose – Seek to compare the consequences of single‐source versus multiple‐source lending for a borrower who has loans that can be prematurely terminated. Design/methodology/approach – The considered model framework is an option‐theoretic firm value model similar to Merton (1974) but...

This paper shows that the consistent way of modeling sentiment‐driven moral behaviors in a setting of social interaction is to derive the equilibrium moral code that is mutually consistent with the optimal moral behavior of each player. To do this, it is necessary that moral sentiments be...

Purpose – The purpose of this paper is to suggest possible extensions of the baseline Rubinstein sequential bargaining structure – applied to the negotiation of stationary infinitely termed contracts – that incorporate a direct reference to the “ideal” utilities of the players. This is...

Purpose – The purpose of this paper is to construct an econometric model of the determinants of private investment with a particular focus on the impact of democracy on investment. Design/methodology/approach – The first step was to econometrically derive the long‐run elasticities; then to...

Purpose – Henry George was acclaimed by the general public and disdained by the professional economists, largely for the same reasons. For the general public, progress, and poverty seemed to go to the heart of the matter, treating economics as a question of justice. But for the professionals,...
