در این مطالعه، ارتباط بین کارایی مقیاس و تمرکز صنعتی در 22 صنعت مواد غذایی و آشامیدنی در ایران، برای سال های 1376- 1386، بررسی می­گردد. در این راستا، ابتدا کارایی مقیاس و سپس تمرکز صنعتی، با استفاده از شاخص هرفیندال- هیرشمن، محاسبه شده است. هم چنین رابطه علیت میان دو متغیر کارایی مقیاس و تمرکز، با استفاده از آزمون علیت گرنجر، مشخص شده است. نتایج نشان دهنده آن است که یک علیت یک طرفه از متغیر تمر...

In this paper we provide further results on the properties of the IV estimator in the presence of weak instruments.We begin by formalizing the notion of weak identi ̄cation within the local-to-zero asymptotic framework of Staiger and Stock (1997), and deriving explicit analytical formulae for the asymptotic bias and mean square error (MSE) of the IV estimator. These results generalize earlier ̄n...

The paper analyses the impact of geographic innovation on Total Factor Productivity (TFP) in Taiwan in 2001 using 242 four-digit standard industrial classification (SIC) industries. We compute TFP by estimating Translog production functions with K, L, E and M inputs, and measure the geographic innovative activity using both Krugman's Gini coefficients and the location Herfindahl index. We also ...

The endogeneity of optimum currency areas criteria has been widely studied since Frankel and Rose (1998) seminal paper. Literature normally suggests that there is a positive relationship between trade and business cycles correlation. This paper develops work on this subject (Silvestre and Mendonça, 2007) where we confirm this hypothesis in euro area countries and UE-15 for 1967-2003 period usin...

This paper examines the unexplored link between the prevalence of overweight and obesity and vehicle demand in the United States. Exploring annual sales data of new passenger vehicles at the model level in 48 U.S. counties from 1999 to 2005, we find that new vehicles demanded by consumers are less fuel-efficient on average as a larger share of people become overweight or obese. The OLS results ...
