Testing a DSGE Model of the EU Using Indirect Inference

We use the method of indirect inference, using the bootstrap, to test the Smets and Wouters model of the EU against a VAR auxiliary equation describing their data. We find that their model generates excessive variance compared with the data. But their model fits the dynamic facts quite well if the errors have the properties assumed by SW but scaled down. We compare a New Classical version of the model which also performs reasonably if error properties are chosen using New Classical priors (notably excluding shocks to preferences). Both versions have (different) difficulties fitting the data if the actual error properties are used. A model combining rigid and flexible-wage/price sectors, with a weight of around 5% on the rigid sector, does best in fitting the data.     

Income inequality and education revisited: persistence,endogeneity and heterogeneity

This article presents new results on the relationship between income inequality and education expansion – that is, increasing average years of schooling and reducing inequality of schooling. When dynamic panel estimation techniques are used to address issues of persistence and endogeneity, we find a large, positive, statistically significant and stable relationship between inequality of schooling and income inequality, especially in emerging and developing economies and among older-age cohorts. The relationship between income inequality and average years of schooling is positive, consistent with constant or increasing returns to additional years of schooling. While this positive relationship is small and not always statistically significant, we find a statistically significant negative relationship with years of schooling of younger cohorts. Statistical tests indicate that our dynamic estimators are consistent and that our identifying instruments are valid. Policy simulations suggest that education expansion will continue to be inequality reducing. This role will diminish as countries develop, but it could be enhanced through a stronger focus on reducing inequality in the quality of education.     

The impact of stocks and flows of organizational knowledge on firm performance: an empirical investigation of the biotechnology industry

The knowledge‐based view of the firm is a recent approach to understanding the relationship between firm capabilities and firm performance. Specifically, this approach suggests that knowledge generation, accumulation and application may be the source of superior performance. Other research has conceptualized organizational knowledge in terms of stocks of accumulated knowledge in the firm and flows of knowledge into the firm. This paper tests the relationship between stocks and flows of organizational knowledge and firm performance in the biotechnology industry. We suggest that a firm’s geographic location, alliances with other institutions and organizations and R&D expenditures are representative of knowledge flows, while products in the pipeline, firm citations and patents are indicative of knowledge stocks. Through factor analysis, we develop an aggregated measure of location from several variables. A regression model suggests that location is a significant predictor of firm performance as are products in the pipeline and firm citations. A major contribution of this investigation is the operationalization of geographic location and its statistically significant link to firm performance. Copyright © 1999 John Wiley & Sons, Ltd.     

Economic contribution of French serradella (Ornithopus sativus Brot.) pasture to integrated weed management in Western Australian mixed‐farming systems: an application of compressed annealing*

Sowing phases of French serradella (Ornithopus sativus Brot.) pasture between extended cropping sequences in the Western Australian wheatbelt can sustain grain production through restoring soil fertility and reducing selective herbicide use. The objective of this article is to investigate the profitability of rotations involving this pasture under a variety of weed management scenarios to obtain greater insight into its value for mixed farming systems in this region. A stochastic search procedure, compressed annealing, is used to identify profitable sets of weed management strategies in a simulation model representing a large number of potential combinations of chemical and non‐chemical forms of weed control. In contrast to a continuous‐cropping sequence, the inclusion of a serradella phase in a rotation is profitable at high weed densities and with increasing levels of herbicide resistance. A single year of pasture in the rotation is optimal if resistance to Group A selective herbicides is present at the beginning of the planning horizon, but a three‐year phase is required if resistance to multiple herbicide groups is observed. Sowing a serradella pasture twice over a two‐year phase is also shown to be economically attractive given benefits of successive high weed kills.     

Clubs as a case of competitive industry with goods of variable quality

The paper provides a new proof for the optimality of market provision for Buchanan's club goods where club goods are treated as goods of variable quality. This approach extends the theory of clubs, and introduces congestion to the analysis of competitive equilibrium with goods of variable quality.     

A theory of development controls in a ‘small’ city

This paper analyzes the implications of an institutional structure in which current residents of an urban area have the power to exercise control over the level and pattern of new residential development. We develop a general equilibrium spatial model of a ‘small’ urban area in which the current residents can control new residential development through a zoning policy determined by majority vote. The current residents are modeled explicitly as home owners, and are allowed to be arbitrarily different in tastes and endowments. The urban government is assumed to provide a public good for its residents, the level of which is also determined by majority vote.The ‘optimal’ development control policy from the point of view of a particular current resident is determined and the allocation resulting from a majority vote of the current residents is described for both head tax and property tax systems. Efficient development control policies are also analyzed.     

In search of a residual dividend policy

We survey 309 sample firms exhibiting behavior consistent with a residual dividend policy and their matched counterparts to learn how they set their dividend policies. The findings reveal that the sample firms are more likely than their counterparts to maintain a long-term dividend payout ratio, use long-run earnings forecasts in setting the dividend, and be unconcerned about the cost of raising external funds. Yet, firms behaving as though they follow a residual dividend policy generally do not profess to follow the policy. At best, the sample firms follow a “modified” residual policy in which they carefully manage their payout ratio and dividend trend. Although it may not be an explicit goal of such a dividend policy, consistently low free cash flow typically results.
