College Attainment of Women

Up to the late 1970's the Sex College Attainment Ratio (SCAR), or ratio of college attainment between men and women, was about 1.6. Assortative mating within education groups in marriages is strong enough in the United States to prevent accounting for the SCAR feature based on males' higher earnings. We document the puzzling nature of the SCAR, and we explore various theories to account for it. Our main finding is that if parents' well-being is affected by the number of grandchildren, gender differences in the steepness of the negative relation between educational attainment and number of children provides the best theory to understand the SCAR.

Television advertising television: measuring the ability of television promos to deliver ratings for new programs using single-source data

The entertainment industry relies heavily on advertising to attract audiences. This article demonstrates a method to measure the effect of on-air television promotions, or promos, on viewing behaviour, based on a well-established single-source method for determining the causal impact of advertising on sales. We illustrate this method on 18 new prime-time programs, showing that promos have a positive impact on viewing behaviour. Exposed viewers are substantially more likely to view the premiere episode of a new series, across a wide range of different television-viewing weights, frequency of promo exposures and program types. The research also shows evidence of reach-based scheduling strategies being generally more efficacious than frequency-based strategies. These findings provide guidance to help networks implement their promo strategy more effectively, as well as a method for future research into the effectiveness of television promos as this approach can be utilized in any country with a television ratings panel.     

Surpluses in Disequilibrium Urban Land Markets

It is unlikely that urban land markets are in equilibrium. If land markets are out of equilibrium, zones within an urban area would have residential location surpluses. This paper shows how to derive and estimate an index of income surplus by residential zone. The procedure is applied to the Baltimore Metropolitan Area for 1978. Households should be at attracted to zones with high surpluses. A comparison of the estimated location surpluses and growth rates for the Baltimore area show this correspondence.

Abstract

This study provides an economic analysis of life insurance company expenses and develops a methodology for the construction of benchmark expense factors. These benchmarks can facilitate the pricing of new business, cost control within companies, and expense comparisons among companies. We derive the expense factors by estimating a cost function wherein total general expenses are modeled as a function of input prices and physical outputs, and the physical outputs are proxies for the cost drivers of the different lines of business. This methodology has two important advantages: first, the derived expense factors are independent of the methods that insurers use in allocating total expenses across lines of business. Second, the estimated cost function explicitly accounts for different degrees of economies of scale and consequently in the present value of marginal expenses across insurers. Hence, this study demonstrates that economies of scale and, in turn, size must be considered when constructing an expense table.     

Spain is different: Falling trends of inequality

In this article we characterize the evolution of inequality in hourly wages, hours of work, labor earnings, household disposable income and household consumption for Spain between 1985 and 2000. We look at both the Encuesta Continua de Presupuestos Familiares and the European Household Community Panel. Our analysis shows that inequality in individual net labor earnings and household net disposable income has decreased substantially. The decreases in the tertiary education premium and in the unemployment rate have been key ingredients to understand this falling trend. Public transfers have played a crucial role in smoothing out the inequality arising in the labor market, but instead the Spanish family does not seem to have been an important insurance mechanism. Regarding household consumption, inequality has fallen much less than inequality in household net disposable income, with the decrease mostly concentrated in the second half of the eighties. This suggests that the reduction in income inequality has affected the sources of permanent differences between households only during the second half of the eighties. Our estimates of the earnings process for the period are consistent with this view.     

Collective Voice under Decentralized Bargaining: A Comparative Study of Work Reorganization in US and German Call Centres

This article compares the process of and outcomes from work reorganization in US and German call centres, based on four matched case studies in the telecommunications industry. Both German cases adopted high‐involvement employment systems with broad skills and worker discretion, while the US cases relied on a narrow division of labour, tight discipline and individual incentives. These outcomes are explained by differences in institutional supports for collective voice. Works councils in the German companies used their stronger participation rights to limit monitoring and encourage upskilling at a time when US managers were rationalizing similar jobs. Findings demonstrate that industrial relations institutions can have a substantial influence on employment systems in work settings characterized by decentralized bargaining and strong cost pressures.     

Prior knowledge and social networks in the exploitation of entrepreneurial opportunities

In this study we analyze the effects of prior knowledge and social networks on the exploitation of entrepreneurial opportunities. The prior knowledge considered is associated with the successes and failures experienced in the entrepreneurial trajectory and, therefore, derived from the exploitation of prior opportunities. In analyzing social networks, we examine the strength of the relationships between entrepreneurs, managers and entrepreneurial associations. As an explanatory factor of the entrepreneurial process, we also include the influence of the entrepreneurial opportunities recognized. Through a hierarchical regression analysis, we show that the number of potential opportunities recognized, the number of previous opportunities successfully exploited and the strength of entrepreneurial social networks positively influence the number of opportunities developed and exploited.     

Technology investment and alternative regulatory regimes with demand uncertainty

A vertically integrated incumbent and an OLO (Other Licensed Operator) compete in the market for broadband access. The incumbent has the option to invest in building a Next Generation Network that covers all urban areas with similar demand structures. The investment return in terms of demand increase is uncertain. We compare the impact of different access regulation regimes – full regulation, partial regulation (only the copper network is regulated), risk sharing – on investment incentives and social welfare. We find that, when the alternative for the OLO is using the copper network rather than leaving the market entirely, exclusion of the OLO does not necessarily happen in equilibrium even when the incumbent is better in offering value-added services. Risk sharing emerges as the most preferable regime both from a consumer and a social welfare perspective for a large range of parameters.     

Transparency to Reduce Corruption?

Corruption within the private sector has often not been dealt with in Brazil. Organizations may find corrupt acts in its operations or practices, but specific concepts and programs to avoid them are neither concrete nor clear. Some Brazilian stockholders have become aware of the risks involved in unethical procedures and are adopting the Best Practices of Corporate Governance initiative. International agencies have intensively supported organizations and governments in an effort to define policies that inhibit illegal or corrupt cultural habits throughout the world, but Brazilian practitioners show insufficient response. Skepticism may indicate a lack of understanding about how an ethical leadership can guide employees, setting high standards for the organizational culture and climate, clearly defining limits of correct behavior, and creating appropriate codes of ethics. Transparency still has to be discovered as a significant tool to encourage professionalism in performance and reporting of data in Brazilian companies. In this article, we analyze the ethical behavior of the purchasing department of a multinational company in its host country, Brazil. It focuses specifically on the supplier–buyer relationship. The results indicate that despite the negative reputation Brazilians have in business ethics, a company can still develop a positive and ethical relationship with its stakeholders. Communication, transparency, compliance with the company’s code of conduct as well as the supplier’s awareness of the buyer’s code of conduct are the factors which influence the supplier–buyer relationship. Transparency can be used as a tool to reduce corruption, thereby increasing ethical behavior and company image. Good ethical behavior can help to build up a company’s image.     

Pricing Dynamic Insurance Risks Using the Principle of Equivalent Utility

We introduce an expected utility approach to price insurance risks in a dynamic financial market setting. The valuation method is based on comparing the maximal expected utility functions with and without incorporating the insurance product, as in the classical principle of equivalent utility. The pricing mechanism relies heavily on risk preferences and yields two reservation prices - one each for the underwriter and buyer of the contract. The framework is rather general and applies to a number of applications that we extensively analyze.
