We construct a new database by matching firm-level Compustat data to NBER patent data, for four 2-digit complex technology sectors. Whilst conventional regression estimators show that the stock market does recognise efforts at innovation, quantile regression analysis adds a new dimension to the...

This article tackles one central issue in the regional science literature: the persistence of regional disparities in unemployment within national economies. Our approach is original as Okun's coefficients are estimated for each of the 22 administrative French regions over the period...

Empirical studies use the total area as a measure of land factor. This measure is flawed as it ignores the effectiveness of that total area. We develop an estimator of effective area based on spatial population distribution. The empirical application for the OECD countries highlights the...

This paper explores the population distribution across U.S. states over time. We test for Zipf's Law on the size distribution of state populations and Gibrat's Law for the growth of state populations. State populations follow a lognormal distribution more closely than they do a Zipf or Pareto...

In the two-country Melitz (2003) model, unilateral trade liberalization is often cast as a reduction of iceberg transportation costs and wages are determined by a linear outside sector. We show that welfare results reverse when wages adjust and trade frictions are revenue-generating tariffs.

We studied how links are formed according to the distance in transaction network of 800,000 firms. We investigated the inter-firm transaction network of $800,000$ firms in Japan. They are almost all firms in Japan. As far as we know, scale-freeness, hierarchy, and degree-degree correlation were...

This paper examines both the long-run and short-run relationships among the four regional housing markets in Taiwan, under the structural change framework. The empirical results demonstrate that the regional housing markets have a cointegration relationship and the long-run relation has two...

The present paper empirically investigates the cointegrating relation between housing prices and economic fundamental variables in the US housing market. Employing simple yet rigorous econometric techniques, the present paper finds strong evidence in favor of cointegrating relations in most US...

Using official census data for the province of Istanbul, we identify the determinants of the support for the Justice and Development Party (AKP) which has been in power in Turkey since 2002. District-level socio-demographic indicators such as the gender gap in education and the mean age - which...
