Using administrative data from the state of Georgia, this paper finds that, on average, across all firms, employing undocumented workers reduces a firm’s hazard of exit by 19 percent. The advantage to firms from employing undocumented workers increases as more firms in the industry do so, decreases with the skill level of the firm’s workers, increases with the breadth of a firm’s market, and in...

Employment Effects of Payroll Taxes An Empirical Test for Germany* This study tests to what degree the incidence of payroll taxes in Germany is on employment and whether in consequence payroll taxes, in particular social insurance contributions, are the culprit behind the growing unemployment problem. Using industry level data for 18 years (1977-1994) we estimate a system of five interdependent...

It is a widely adopted practice for firms to announce new products well in advance of actual market availability, especially in the computer industry. In this paper, a firm makes pre-announcements on its product, which are ‘cheap talk.’ We develop a reputation model of vaporware where the product pre-announcement can convey information about the product’s quality. Also, we discuss its implicati...

Drastic changes and turbulence in macro-economic factors have the greatest impact on banks target market attractiveness in Iran. It is assumed that conventional segmentation models at the corporate level are not efficient for banking system. This study aims to develop a new segmentation model at the industry level for banks of Iran. For this purpose, structures and variables at the industry lev...

In this paper, the problem of automatic classification of rust grades on steel surfaces is considered. Three texture analysis methods are studied to form features from steel surfaces. Nearest Neighbor classifier is used for classification of steel surface types. The results indicate that automation of the inspection and classification process is feasible.

Linkages between industry and university have become crucial for knowledge discovery and driving industrialization within fast-paced global competition and technological evolution. This study offers a pair-wise cross-case analysis of the transitioning of Pohang University of Science and Technology (POSTECH) and Sungkyunkwan University (SKKU) to become entrepreneurial universities through the Co...

U.S. stock portfolios sorted on size, momentum, transaction costs, M/B, I/A and ROA ratios, and industry classification show considerable levels and variation of return predictability, inconsistent with asset pricing models. This means that a predictable risk premium is not equal to compensation for systematic risk as implied by asset pricing theory (Kirby 1998). We show that introducing market...

This paper addresses the problem of the general validity of models of the industry life cycle, which have been proposed to analyse the long-term evolution of many industries, exhibiting a typical pattern of shakeout. We study a case of non shake-out in the commercial jet aero-engine industry, marked by a small number of entry events distributed over 40 years of industry evolution, by no exits a...

Industries are economically linked through customer-supplier trade flows. We show theoretically and empirically that industry shocks propagating along this inter-sectoral trade network can feed back to the originating industry, causing an “echo” – intermediate-term autocorrelation in returns. Adopting techniques from graph theory, we find that the strength of the trade network feedback is a cru...
