Enforcement of Intellectual Property,Pollution Abatement,and Directed Technical Change

We theoretically investigate the interaction between endogenous enforcement of intellectual property rights (IPRs) and tax-financed pollution abatement measures. IPRs affect dirty and clean intermediates alike such that higher IPR enforcement may promote the transition to the clean technology, if this technology is productive enough. If the green technology is relatively unproductive, higher IPRs promote the dirty technology while pollution is increasing. As households are due to subsistence consumption subject to a hierarchy of needs, the level of IPR enforcement as well as the level of abatement measures depends on the state of technology and is increasing during economic development. Thus, if the incentive to enforce IPRs is low the level of abatement measures is also low. This argument provides a theoretical foundation for the observed clash of interests in international negotiation rounds regarding the harmonization of IPR protection and actions to combat climate change.     

Influence Costs, Structural Inertia, and Organizational Change

This paper builds an economic model of the relationship between influence activity and resistance to change in organizations. I show that influence activity can create harmful barriers to change and that the influence costs of change are positively related to the firm's prospects. The model rationalizes the widely held view that firms often must endure a survival-threatening crisis before meaningful change can be achieved. I show that employees' choices of whether to engage in influence activity can depend on their beliefs as to whether the firm will choose to change its organizational form. If employees expect change, their best response is to try to affect the form of the change in their favor.     

Recent Changes in British Wage Inequality: Evidence from Large Firms and Occupations

Using a linked employer–employee dataset covering large firms, we present new evidence on British wage inequality trends over the past two decades. Differences between firms in the average wages they paid did not drive these trends. Between 1996 and 2005, greater wage variance within firms accounted for 86% of the total increase in wage variance among employees. In the following decade, wage inequality between firms continued to increase, whereas overall wage dispersion decreased. Approximately all the contribution to inequality dynamics from estimated firm-specific factors, throughout the employee wage distribution, disappears after accounting for the changing occupational content of wages.     

Currency devaluations and beggar-my-neighbour penalties: evidence from the 1930s

The currency devaluations of the 1930s facilitated a faster recovery from the Great Depression in the countries depreciating, but their unilateral manner provoked retaliatory and discriminatory commercial policies abroad. This article explores the importance of the retaliatory motive in the imposition of trade barriers by gold bloc countries during the 1930s and its effects on trade. Relying on new and existing datasets on the introduction of quotas, tariffs, and bilateral trade costs, the quantification of the discriminatory response suggests that these countries imposed significant beggar-my-neighbour penalties. The penalties reduced trade to a similar degree that modern regional trade agreements foster trade. Furthermore, the analysis of contemporary newspapers reveals that the devaluations of the early 1930s triggered an Anglo-French trade conflict marked by tit-for-tat protectionist policies. With regards to global trade, the unilateral currency depreciations came at a high price in political and economic terms. These costs must have necessarily reduced their benefit to the world as a whole.     

Analysts’ forecast revisions and firms’ research and development expenses

This study examines whether reported values for firms’ research and development (R&D) affect analysts’ annual earnings forecast revisions following quarterly earnings announcements. Because R&D introduces uncertainty into earnings forecasts, analysts may benefit from additional information searches in an effort to increase forecast accuracy. Also, accounting standards mandate an immediate expensing of R&D, in essence projecting a zero value for the R&D. To the extent that R&D will produce future payoffs, the expense treatment reduces the informativeness of reported earnings for forecasting future earnings. Thus, the marginal benefit of analysts’ efforts to produce more information may increase with the magnitude of the R&D component of earnings announcements and trigger additional forecast revisions. Alternatively, if the cost of information searches exceeds the benefit, analysts’ forecast revisions may decrease. Our results show a positive relation between R&D expenses and analysts’ forecast revision activity. We also find a positive and significant association between the level of R&D expenses and the magnitude of analysts’ forecast revisions following quarterly announcements. These results point to a greater amount of analyst scrutiny when reported earnings are accompanied by high levels of R&D expenses.

Berry-Esseen-type inequality for a special class of distributions

LetQ be the distribution of the suitably normalized sum of i. i. d.k-dimensional random vectors (k2) and letf be a measurable real valued function of the formf(z ₁,...,z _k )=z ₁+r(z ₂,...,z _k ), where the measurable functionr fulfills certain regularity conditions. A Berry-Esseen-type inequality is derived for the one-dimensional distributionP=Qf ^–1.     

AFDC and births to unwed women

Most studies by economists have been inconclusive when seeking a consistent relationship between income-support programs [like aid to families with dependent children (AFDC)] and births to unwed women (or, as the literature traditionally terms it, illegitimacy). But a recent study [Southern Econ. J. 62 (1995) 44] reports a large, positive and statistically significant relationship when data are weighted to reflect differences in propensities toward illegitimacy. We find that the 1995 study appears to rely upon erroneous data and irregular econometric technique. When these are remedied, the major results are reversed. We then suggest that a switching regimes methodology, with parameters influenced by other variables, is more appropriate to the issue. Our empirical results confirm the literature's consensus that AFDC and illegitimacy do not appear to be strongly related.
