Inter‐state dynamics of invention activities, 1930–2000

We study the dynamics of the cross‐section distribution of patents per capita for the 48 continental US states from 1930 to 2000 using a discrete‐state Markov chain. We test for and find evidence in favor of the (knowledge) convergence hypothesis. The distribution of patents is converging to a limiting distribution that is significantly more concentrated than its initial distribution. States in the extreme are more mobile than states in the middle of the cross‐sectional distribution and are likely to move to the middle. However, the rate of convergence to the limiting distribution is ‘slow’. Copyright © 2006 John Wiley & Sons, Ltd.     

Vertical externality and strategic delegation

This paper examines the effects of vertical externality generated by the upstream monopoly on the incentives that owners of competing downstream firms give their managers. It is shown that the introduction of the upstream monopoly may have significant effects on the incentive schemes for the downstream firms' managers. In particular, it is shown that in equilibrium, each owner obtains the simple Nash equilibrium outcome regardless of the mode of competition (quantity or price) in the downstream market.

Consumer product search and purchase behaviour using various retail channels: the role of perceived retail usefulness

The purpose of this study was to examine the influences of consumers' perceptions of retail usefulness for product information search and their previous purchase satisfaction on their frequencies of product information search and product purchase behaviours for apparel products. These relationships were investigated in five retail settings – Internet shopping, catalogue shopping, television shopping, local retail shopping, and non‐local retail shopping. One hundred seventy‐six students in a US Midwestern university provided usable responses. The results of causal model analyses showed that the proposed model fits the data well for all five retail channels. Consumers who perceived a certain retail channel more useful for product information search searched for product information more frequently via that retail channel, and purchased products more often via that retail channel. Consumers who were more satisfied with apparel purchases from a retail channel purchased the products more frequently via that retail channel. Theoretical and managerial implications are discussed.     

Publishing performance of Spanish academics: 1970—2004

This work complements some of the results appearing in the article “Publishing Performance in Economics: Spanish Rankings” by Dolado et al. (Span Econ Rev 5: 80–103, 2003) Specifically we focus on the robustness of the results regardless of the time span considered, the effect of the choice of a particular database on the final results, and the effects on changes in the unit of institutional measure (departments vs. institutions as a whole). Differences are significant when we expand the time period considered. There are also significant but small differences if we combine datasets to derive the rankings. Finally, department rankings offer a more precise picture of the situation of the Spanish academics, although results do not differ substantially from those obtained when overall institutions are considered.     

Corporate Social Responsibility and Family Business in Spain

Despite the economic relevance and distinctiveness of family firms, little attention has been devoted to researching their nature and functioning. Traditionally, family firms have been associated both to positive and negative features in their relationships with the stakeholders. This can be linked to different orientations toward corporate social responsibility. Thus, this research aims to identify the approaches that Spanish family firms maintain about social responsibility, based on the model developed by Quazi and O Brien Journal of Business Ethics 25, 33–51 (2000). An empirical study carried out for 112 Spanish family firms gives support to our initial assumption about these organizations not being a homogeneous group in terms of their orientation towards corporate social responsibility. The differences in perceptions do not seem to be associated to biographical characteristics. These results lead to some relevant academic and practical implications that suggest interesting lines for future research.María de la Cruz Déniz Déniz is professor in the Department of Management at Las Palmas de Gran Canaria University (Spain).

Market Consequences of Earnings Management in Response to Security Regulations in China*

Under the 1996‐98 security regulations in China, the accounting rate of return on equity (ROE) has to be greater than 10 percent for three "consecutive" years for a firm to qualify for stock rights offers. Despite declining economic conditions during this period, the percentage of firms reporting ROE between 10 and 11 percent is about "three" times that for 1994‐95. This unique regulatory environment provides a natural experimental setting for the empirical assessment of earnings‐management behavior and its consequences. This study examines whether listed Chinese firms manage earnings to meet regulatory benchmarks and whether regulators and investors consider the quality of earnings in their respective regulatory and investment decisions. On the basis of a sample of listed Chinese firms from 1996 to 1998, we observe that managers execute transactions involving below‐the‐line items and use income‐increasing accounting accruals to meet regulatory ROE targets for stock rights offerings. The firms that apply for, but fail to receive, regulatory approval manage earnings more significantly than do firms that receive approval and pair‐matched control firms. Our market study also suggests that investors differentiate the quality of earnings and put less value on earnings suspected of a greater degree of management. Overall, our results imply that the regulatory bodies and investors to some extent make rational adjustments for the quality of earnings.     

Hyperbolic Efficiency and Parametric Distance Functions: With Application to Spanish Savings Banks

Distance functions are gaining relevance as alternative representations of production technologies, with growing numbers of empirical applications being made in the productivity and efficiency field. Distance functions were initially defined on the input or output production possibility sets by Shephard (1953, 1970) and extended to a graph representation of the technology by Färe, Grosskopf and Lovell (1985) through their graph hyperbolic distance function. Since then, different techniques such as non parametric-DEA and parametric-SFA have been used to calculate these distance functions. However, in the latter case we know of no study in which the restriction to input or output orientation has been relaxed. What we propose is to overcome such restrictiveness on dimensionality by defining and estimating a parametric hyperbolic distance function which simultaneously allows for the maximum equiproportionate expansion of outputs and reduction of inputs. In particular, we introduce a translog hyperbolic specification that complies with the conventional properties that the hyperbolic distance function satisfies. Finally, to illustrate its applicability in efficiency analysis we implement it using a data set of Spanish savings banks.     

Fiscal policy and private consumption behaviour: The Spanish case

In this article we analyse whether the Ricardian equivalence hypothesis is a valid approximation for Spains economic reality or whether there exist deviations from that situation which would be more in line with the conventional Keynesian perspective of the effects of debt on private consumption-savings decisions.Our aim is to contribute to the rather sparse empirical literature on the subject for the Spanish case. The analysis is based on annual aggregate data for Spain covering the years 1955 to 2000, and uses both the structural and the Euler equation approaches to test the neutrality proposition, and is thus to be considered as a generalization of foregoing work on the Spanish economy.The findings indicate that support for Ricardian equivalence is mixed, while we also find very little support for the Keynesian specification of consumption and fiscal policy.First revision received: March 2003 / Final version received: October 2003The authors wish to thank M.

Methods for Environmental and Economic Accounting for the Exploitation of Wild Fish Stocks and their Applications to the Case of Icelandic Fisheries

The paper discusses methods for estimating the value of commercially exploited fish stocks and the cost of exploiting them. Methods which are recommended in the System of National Accounting (SNA) satellite system and the System for Integrated Environmental and Economic Accounting (SEEA) and relevant for this task are discussed. The paper questions the relevance of some of these methods. It argues for the integration of economic accounting for wild fish stocks with estimation of efficient management of them. Using biological and economic data makes it possible to produce consistent estimates of the value of fish stocks and the cost of exploiting them. These estimates are useful for national accounting and for guiding management of fisheries. This method allows estimation of the cost of inefficiency of fisheries management besides estimation of the cost of depletion. The different methods are illustrated using data on commercial fisheries in Iceland and the fish stocks that they exploit. It is shown that even if all methods are based on market valuation and use only objective data they lead to very different outcomes.     

Technological learning,technological substitution,and technological change

From a simple dynamic model of competition between product lines it is shown that the shape of learning curves has a powerful influence on the dynamics of technological substitution. Learning of both production efficiency and marketing efficiency is considered. It is asserted that both types of learning are important and that the two are complementary. It is further speculated that production learning is probably more important for commodities and in situations of low per capita income, whereas market learning gains ascendancy in cases of high income and specialized and diversified product lines. In closing, it is noted that simple competitive models are misleading, first because complementarities and coevolutionary processes are probably as important in the overall development of technology as are competitive processes, and second because optimization of the technological system's parts does not guarantee improvement of the performance of the system as a whole.
