This paper examines the impact of the immigration of foreigners on domestic labor mobility. Since David Card's seminal study on the regional labor market impact of the Mariel Boatlift it is controversial whether domestic labor mobility equilibrates economic conditions across regions. However, there is little or no evidence that natives leave destinations where migrants tend to cluster. In this paper we reconcile the existing evidence by taking another route: we analyze whether the immigration of foreigners replaces domestic mobility from poor to rich regions. We focus on Italy, which is characterized by large North-South wage and unemployment differentials, and apply panel cointegration methods. The main finding is that, conditional on unemployment and wage differentials, the presence of foreign workers in the labor force of the destination regions discourages internal labor mobility significantly. As a consequence, spatial correlation studies which use the variance of the foreigner share across regions for identifying the wage and employment effects of immigration, tend to understate the actual impact of foreign immigration. 相似文献

Using a panel of 79,841 Chinese firms over the period 2000-2007, we examine the extent to which liquidity constraints affect firms' assets growth. We find that state owned enterprises are not affected, while the availability of internal finance represents a binding constraint for the growth of private firms, especially those operating in coastal regions, with negligible foreign ownership. Thanks to their high productivity, cash flow is, however, so abundant for these firms that they are able to grow at a very fast rate, despite being discriminated against by financial institutions. Hence, well developed external capital markets may not always be needed for fast economic growth. 相似文献

The usefulness of carbon disclosures has been questioned in the literature because they do not truly reflect firm’s carbon performance, suggesting that they may not be useful for risk evaluation and investment decisions. This study empirically tests the usefulness of carbon information voluntarily disclosed by the Italian firms. Our results based on the price model show that there is a positive association between the stock price and carbon disclosures, suggesting that investors find carbon information useful for their investment decisions. We find similar results based on the market valuation model. Additionally, the results reveal that the positive association is especially strong for firms that have established environmental committees on a voluntary basis and also for firms from the highly polluting industries defined by the EU_ETS program, confirming that investors’ positive response is especially strong to carbon disclosures by firms from the highly polluting industries. We also find that the market reacts positively to carbon disclosures by firms with a higher percentage of independent directors on their corporate boards, but the positive association is marginally significant. 相似文献

History provides many examples of cohesive groups dispersed over several countries who exploit the ties between their members to gain entry into foreign markets. The phenomenon is well-established empirically and noteworthy because it suggests the importance of informational barriers in international transactions. We present a simple model where output is produced through a joint venture, and agents have complete information domestically but are unable to judge the quality of their match abroad. A minority of individuals, otherwise identical to all others, can exploit complete information in international matches between group members, if they so choose. Group ties increase aggregate trade and income, but hurt the anonymous market because they deprive it disproportionately of the group’s more productive members. 相似文献

We use a panel of over 116,000 Chinese firms of different ownership types over the period 2000–2007 to analyze the linkages between investment in fixed and working capital and financing constraints. We find that those firms characterized by high working capital display high sensitivities of investment in working capital to cash flow (WKS) and low sensitivities of investment in fixed capital to cash flow (FKS). We then construct and analyze firm-level FKS and WKS measures and find that, despite severe external financing constraints, those firms with low FKS and high WKS exhibit the highest fixed investment rates. This suggests that an active management of working capital may help firms to alleviate the effects of financing constraints on fixed investment. 相似文献

In this paper, we use individual micro data on workers combined with industry and regional data to study the wage dynamics of skilled and unskilled workers in Italy in the 1991–1998 period. In contrast to previous empirical studies, our data make it possible to analyse, within a single framework, the role of many of the factors indicated in the literature as possible determinants of skilled and unskilled wage dynamics: changes in the individual characteristics of workers, changes in labour market institutions, increasing international integration, and skill‐biased technological progress. Our results show that international integration, both in terms of trade in goods and in terms of international labour mobility, plays a role in determining the wage dynamics of skilled (white‐collar) and unskilled (blue‐collar) workers. Moreover, in line with labour economics research, our findings show that the individual characteristics of workers and the institutional variables are more relevant in explaining skilled and unskilled wage dynamics than wage differentials. 相似文献

We wish to study inter-rater agreement comparing groups of observers who express their ratings on a discrete or ordinal scale.
The starting point is that of defining what we mean by “agreement”. Given d observers, let the scores they assign to a given statistical unit be expressed as a d-vector in the real space. We define a deterministic ordering among these vectors, which expresses the degree of the raters’
agreement. The overall scoring of the raters on the sample space will be a d-dimensional random vector. We then define an associated partial ordering among the random vectors of the ratings, illustrate
a number of its properties, and look at order-preserving functions (agreement measures). In this paper we also show how to
test the hypothesis of greater agreement against the unrestricted hypothesis, and the hypothesis of equal agreement against
the hypothesis that an agreement ordering holds. The test is applied to real data on two medical observers rating clinical
guidelines. 相似文献
