This paper presents an environment in which firms’ productive heterogeneity passes through to wage dispersion via sequential search and endogenous worker effort levels. Despite small gains from trade, the model is able account for more than two thirds of the measured firm component of wage dispersion. The implied narrow range of worker utility effectively pins down the lowest wage in the distri...

The following are highlights from the new series, Circulation: Cardiovascular Interventions Topic Review. This series will summarize the most important manuscripts, as selected by the editors, that have published in the Circulation portfolio. The objective of this new series is to provide a concise review of significant papers that are relevant to interventional cardiology. The studies included...

Bir eğri veya yüzey akışı; eğer yay uzunluğu ve eğrilik korunursa uzatılamaz olarak adlandırılır. Fiziksel anlamda, elastik olmayan eğri(inextensible flows) akışları herhangi bir gerilme enerjisinin yokluğu ile karakterize edilir. Bu çalışmada 2 ideksli 4 boyutlu ℚ23 ⊂ E24 lightlike koni uzayında doğal Frenet çatısı kullanılarak ifade edilen null x: I → eğrisinin akışı(inextensible edilerek mat...

Recently Acemolgu, Aghion, Bursztyn and Hemous (AER 2012) formulated a model in which a high macroeconomic elasticity of substitution between clean and dirty production represents a crucial condition for green growth. Until now it has never been systematically estimated. Using a novel panel of cross-country sectoral data, we formulate specifications of nested CES production functions that allow...

Two issues related to mapping a multi-sector model into a reduced-form value-added model are often neglected: the composition of intermediate goods, and the distinction between value added productivity and gross output productivity. We demonstrate their quantitative significance for the case of the well known model of Greenwood, Hercowitz and Krusell (1997), who find that about 60% of economic ...

This paper explores the relevance of unknown nonlinearities for growth empirics. Recent theoretical contributions and case-study evidence suggest that nonlinearities are pervasive in the growth process. I show that the postwar data provide strong evidence in favor of generalized non-linearities. I provide two alternative mechanisms for making inference about the effects of production-function s...

Legal simplification may improve the quality of institutions in industrialised countries that developed over-complex legal systems. In theory, this type of regulatory reform promotes economic efficiency, leading to higher levels of productivity and output. In this paper we use a Panel Factor-Augmented VAR approach to measure the long-run impact of legal-simplification programmes in total factor...

We exploit historical data on planned highways, railroads, and exploration routes as sources of exogenous variation, in order to estimate the effect of interstate highways on regional innovation: a 10% increase in a region?s stock of highways causes a 1.7% increase in regional patenting over a five-year period. In terms of the mechanism, we report evidence that roads facilitate local knowledge ...

Environmental pollution and human health problems are becoming serious issues in China. This research focuses on regional differences in productive inefficiencies and attempts to clarify the determinants of inefficiency, accounting economic, environmental and health-related factors. Our dataset includes information of 29 areas in China from 2003 to 2009. We find that after accounting for enviro...

In this paper the time series properties of the outcomes of two different specifications of a nonparametric productivity analysis are compared using data for threeand four-digit U.S. manufacturing industries over the period 1958-96. The first model is standard and does not account for variations of capacity utilization of the production factors whereas the second model does. Correcting for util...
