This paper investigates interactions between exporting and productivity at the firm level, using a panel of firms in the UK
chemical industry. This is both highly technology intensive and the UK’s largest exporting sector. We find exporters are more
productive than non-exporters, but are also on average smaller. This superior productivity performance among exporters appears
to be caused by both self-selection and learning-by-exporting effects. In contrast to other studies, we find learning effects
are significantly positive among new entrants, weaker for more experienced exporters and negative for established exporters.

Diversification Categories in Investment Real Estate 总被引:3,自引:0,他引:3
This paper continues previous work evaluating the benefits of diversification and analyzes the various dimensions within the commercial real estate opportunity set. The database is large and extends through the 1982 downturn in property values. Due to the low levels of systematic risk, current distinctions by region and property type make little sense in a world of costly diversification. More exacting categories combining property type, SMSA growth rate and lease maturity offer promise for more efficient diversification within the real estate portfolio. 相似文献

The UK gas industry has undergone major changes since it was privatised in 1986 as a fully integrated monopoly. The most significant of these has occurred not as a result of the privatisation legislation but by the intervention of the ordinary competition authorities in support of an active industry regulator. While price capping continues to be used as the primary instrument for welfare protection against the still substantial monopolistic powers of the incumbent, new competition (which has been positively encouraged) has had the greater impact on prices and choice. Recently, however, the regulator has encouraged the use of auctions for the sale of storage capacity. This paper considers the merits of auctions and makes a tentative evaluation of their effectiveness. Further use of auctions is recommended but reserve prices are considered inappropriate where monopoly power still remains. 相似文献

We examine income distributions over the last two decades, presenting both non-parametric kernel density estimates and summary measures. Standard errors of summary measures are also reported to facilitate statistical inference. We find a significant increase in private income inequality, but only a modest increase in disposable income inequality, implying an increase in the inequality-reducing effects of income taxes and transfers. Using a semi-parametric procedure developed by DiNardo et al. (1996), we then examine the effects of changes in family characteristics on the distribution of private income, finding that half the increase in inequality is explained by changes in the distribution of employment. 相似文献

Tort reform of the motor accident insurance compensation scheme in the Australian state of New South Wales in 1999 came about as a result of an untested experiment in regulatory negotiation. This article is a first-hand account of the successful attempt to craft a consensual modification of the scheme through deliberations among a working group of service provider representatives. The author, a Canadian lawyer, investigated the prospects for change, acted as chief negotiator, and observed the legislative process that led to the final law reform. 相似文献

Betting markets provide an ideal environment in which to examinemonopoly power due to the availability of detailed information on product pricing. In this paper we argue that the pricing strategies of companies in the U.K. betting industry are likely to be an important source of monopoly rents, particularly in the market for forecast bets. Pricing in these markets are shown to be explicitly coordinated. Further, price information is asymmetrically biased in favor of producers. We find evidence, based on U.K. data, that pricing of CSF bets is characterized by a significantly higher markup than pricing of single bets. Although this differential can in part be explained by the preferences of bettors, it is reasonable to attribute a significant part of the differential as being due to monopoly power. 相似文献

Nelson and Plosser (1982), in a classic paper, failed to find strong evidence against the null hypothesis of a generating process with a unit autoregressive root for thirteen US macroeconomic time series. Perron (1989) claimed that such evidence was available for a majority of these series if the alternative hypothesis was of trend stationarity with a break in 1929. Zivot and Andrews (1992) treated the break date as endogenous, then finding strong evidence agcainst the null for a minority of these series. Our own analysis extends theirs by permitting a break under the null as well as the alternative hypothesis, and allowing for the sequential nature of the testing. Our empirical findings complete the circle. We find no strong evidence against the unit root hypothesis for any of the thirteen Nelson–Plosser series. 相似文献

Employment Contacts and Minority-White Wage Differences 总被引:1,自引:0,他引:1
We study effects of job contacts on wages in inner-city Boston in 1989 and in the 1982 NLSY. Race/Hispanicity differences in wages are not explained by an absence of contacts among minority youths. Rather, in the Boston data, lower wages of black youths are explained by lower "returns" to their contacts. In the NLSY there is little evidence of lower return to black youths' contacts, but there is evidence of lower returns to Hispanic youths' contacts. 相似文献
