We relate innovation to sales growth for incumbent firms in four high-tech sectors. A firm, on average, experiences only modest growth and may grow for a number of reasons that may or may not be related to ‘innovativeness’. However, given that firms are heterogeneous and that growth rates distributions are heavy-tailed, it may be misleading to use regression techniques that focus on the ‘averag...

Necessity spin-offs are organized by employees of incumbent firms to escape deteriorating job conditions. This paper proposes a conceptual model of the spin-off process. Necessity spin-offs are distinguished from opportunity spin-offs on the basis of their triggering events. An empirical analysis of German laser spin-offs traces differences in the performance and determinants of the two types o...

We consider partnerships among risk-averse professionals endowed with (i) a risky and personally-costly production technology and (ii) a personally-costly monitoring technology providing contractible noisy signals about partners’ productive efforts. Partners shirk both production and monitoring tasks because efforts are unobservable. We characterize optimal partnership size, profit shares and i...

This paper examines the employment effects of acquisitions for acquired European firms taking non-random selection of acquisition targets explicitly into account. Following the empirical firm growth literature and theories put forward in the mergers and acquisition (M&A) literature we control for convergence dynamics in firm size and distinguish between different types of acquisitions. Empirica...

We examine the relationship between the degree of foreign ownership and performance of recipient firms, using of panel of 21,582 Chinese firms over the period 2000-2005. We find that joint-ventures perform better than wholly foreign owned and purely domestic firms. Although productivity and profitability initially rise with foreign ownership, they start declining once foreign ownership reaches ...

We analyze the implications of entrepreneurial spawning for a variety of firm characteristics such as size, focus, profitability, and innovativeness. We examine the dynamics of spawning over time. Our model accounts for much of the empirical evidence relating to the relation between spawning and firm characteristics. Firms that have higher patent quality spawn more, as do firms that have higher...

We propose a strategy to identify the complementarity or substitutability among technology bundles. Differences between the observed distribution of technology choices can be subjected to statistical tests. Combinations of technologies that occur with greater frequency than would occur under independence are complementary technologies. Combinations that occur with less frequency are substitute ...

This paper measures the economic impact of climate change on US agricultural land by estimating the effect of random year-to-year variation in temperature and precipitation on agricultural profits. The preferred estimates indicate that climate change will increase annual profits by $1.3 billion in 2002 dollars (2002$) or 4 percent. This estimate is robust to numerous specification checks and re...

This version of September 3, 2006. German chemical manufacturing industry is marked by two major structural changes during 1992–2004. Firstly, number of firms was ranging extensively: from 676 to 901, while only 96 firms represented balanced panel. Secondly, size of the firm dropped considerably—by 88%. This paper is intended to shed light on both phenomena. Based on reliable census data analys...
