This paper analyzes the robustness of the estimate of a positive productivity shock on hours to the presence of a possible unit root in hours. Estimations in levels or in first differences provide opposite conclusions. We rely on an agnostic procedure in which the researcher does not have to...

We study the effects of human capital homogeneity on economic growth with a two-sector model. We model the difference in human capital via a varying efficiency of individual agents in human capital production, alternatively education. Even though mean value of the education efficiency is the...

Researchers have incorporated labor or credit market frictions in isolation within simple neoclassical models to open up a role for institutions, inject realism into their models and examine the impact of these distortions on output and employment. We present an overlapping generations model...

This paper seeks to shed light on how manufacturing job flows and productivity in Argentina were affected during the 1990s by economic reforms in general and particularly by: a) financial shocks, b) labor reforms that change non-wage labor costs, c) trade reforms that alter tariff dispersion, d)...

Recent research shows that observed labor market flows can be explained in search and matching models only by assuming either implausibly large productivity shocks (Hall 2003) or an excessively high degree of real wage rigidity even for new hires (Shimer 2003). If this is not the case, the...

This paper presents a simple Cass-Koopmans-Ramsey AK growth model with heterogeneity that explains how policies that increase income inequality may temporarily boost a country’s income growth rate. Briefly put, a change in policy that reduces redistributive transfers will free up...

In 1943, Paul Rosenstein-Rodan first coined the term “big-push†in his paper about growth in Eastern European economies. In 1989, Murphy et al. characterised the big-push as a static multi-equilibrium aggregate demand spillover model. Based on the model with a factory wage premium by...

This paper presents a simple Cass-Koopmans-Ramsey AK growth model with heterogeneity that explains how policies that increase income inequality may temporarily boost a country's income growth rate. Briefly put, a change in policy that reduces redistributive transfers will free up resources to...

The paper analyses how barriers to communication across social groups affect economy-wide productivity and factor accumulation. Using a dynamic model of an economy that includes a reproducible capital stock (physical or human) and effective labour, social barriers to communication are shown to...

We derive necessary and sufficient conditions for the occurrence of ergodic oscillations and geometric sensitivity in a two-sector model of economic growth with labor augmenting externalities. We transform the Euler equation into a first order backward first order equation. Factor intensity...
