Vouchers for Basic Education in Developing Economies: An Accountability Perspective

Advocates argue that voucher programs can correct the incentiveproblems of education systems in developing economies. An accountabilityperspective, based on a principal-agent framework, was developedto clarify the arguments for and against education vouchers.An assessment of findings on voucher programs in industrialcountries and a review of voucher or quasi-voucher experiencesin Bangladesh, Chile, Colombia, Côte d'Ivoire, and theCzech Republic support the usefulness of the analytic framework.The assessment concludes that the policy relevance of voucherprograms for developing economies remains uncertain. Major voucherinitiatives have been attempted only in countries with a well-developedinstitutional infrastructure. Some studies find favorable benefitsfor at least some population groups, but others find limitedeffects and evidence of increasing social stratification inschools. Whether vouchers lead to better outcomes or greaterstratification appears related to specific contexts, institutionalvariables, and program designs.      

Reporting Discretion and Private Information Communication through Earnings

We model a two-period pure exchange economy where a risk averse manager, who has private information regarding future earnings, is required to issue an earnings report to investors at the end of each period. While the manager is prohibited from directly disclosing her private information, she is allowed to bias reported earnings in the first period, subject to GAAP rules that require that a specified proportion of the bias be reversed subsequently. We show there is a minimum threshold of reversal, such that, when the proportion of required reversal is above this threshold, the manager smooths income and communicates her private information through reported earnings. Consequently, the market attaches greater weight to reported earnings than under a regime that allows no discretion. When the required reversal is below the minimum threshold, the manager increases reported earnings without limit and the equilibrium degenerates. When the manager is not endowed with any private information, the market unravels the "true" earnings and price is unaffected by earnings management. Our results underscore the importance of both allowing and restricting reporting discretion through formal mechanisms.

Learning about foreign markets: A study of Czech SMEs

Drawing on the organizational learning literature, our study examines the role of foreign market knowledge and firm emphasis on technological innovation in the internationalization of small, entrepreneurial firms in the Czech Republic. It is based on a sample of 168 SMEs representing a broad range of manufacturing industries that were founded after the fall of communism and as the Czech economy was transitioning to a more market-based economy. Findings indicate that emphasis on technological innovation is associated with greater acquisition of foreign market knowledge. In addition, our results indicate that emphasis on technological innovation directly and indirectly influences the performance of such SMEs in international markets. Our findings also suggest that foreign market knowledge partially mediates the relationship between firm emphasis on technological innovation and international performance. Implications of our findings from the perspective of theory and practice are discussed.     

A critique of Porter＇s cost leadership and differentiation strategies

Porter identifies high market share with cost leadership, citing GM as a successful practitioner of this strategy. However, GM became a market share leader in the American automobile industry due to a strategy of market segmentation, differentiation and a broad scope shaped during the 1920s. Porter argues that cost leadership and differentiation offer an equally viable path to competitive success. Nevertheless, a differentiation strategy based on superior quality compared to competition is more profitable than cost leadership strategy. It can lead a business to become a market share leader, and consequently even a low-cost leader. Research indicates that differentiation and cost leadership can co-exist. However, Porter insists that each generic strategy requires a different culture and a totally different philosophy. The problem is that Porter＇s generic strategies are too broad. It is not his logic that is flawed, but his basic premise that prescribes cost leadership strategy as the only route to market share leadership, and presents a narrow view of differentiation with a unique product--sold at a premium price--on the one hand, and a ＂standard, or no-frills＂ product on the other. Mintzburg （1988） says Porter＇s cost leadership strategy should be called ＂price differentiation＂： a strategy that is based on a lower price than that of the competition. He suggests that business strategy has two dimensions： differentiation and scope. Thus, setting scope aside, competitive strategy has only one component： differentiation. So, the key question is not whether to differentiate, but how？ First, make customer-perceived quality as the foundation of competitive strategy because it is far more critical to long-term success than any other factor. Second, serve the middle class by competing in the mid-price segment, offering better quality than the competition at a somewhat higher price. It is this path that can lead to market share leadership--a strategy that can be both profitable--and sustainable.     

A three layer multi-item production–inventory model for multiple suppliers and retailers

The paper deals with a production inventory model for various types of items where multiple suppliers, a manufacturer and the multiple non-competing retailers are the members of the supply chain. In this model, each supplier supplies only one type of raw material to the manufacturer. The manufacturer produces a finished item by the combination of certain percentage of the various types of raw materials. The manufacturer produces also multi-items and delivers them according to the demand of the different retailers. Finally, an integrated profit of the supply chain is optimized by optimal ordering lot sizes of the raw materials. A numerical example is provided to justify the proposed model.     

A multi-echelon supply chain model for reworkable items in multiple-markets with supply disruption

The objective of this paper is to develop a multi-echelon supply chain model for multiple-markets with different selling seasons. Here, two suppliers are involved to supply the raw materials to the manufacturer where the main supplier may face supply disruption after a random time and the secondary supplier is perfectly reliable but more expensive than the main supplier. In this article, the manufacturer produces a random proportion of defective items which are reworked after regular production and are sold in a lot to another market just after completion of rework. The retailer sells the finished products in different markets according to seasons. Finally, an integrated expected cost per unit product of the chain is minimized analytically by considering the lot-size ordered as a decision variable. An appropriate numerical example is also provided to justify the proposed model.     

Social contracts,markets and efficiency: Groundwater irrigation in North India

This paper uses primary data to analyze the institutions and informal markets that govern groundwater allocation in a sugarcane-cultivating village in North India. We find that, in contrast to earlier literature, the observed water trades result in efficient water allocation across farms. We interpret this and other stylized facts in terms of a social contract using a simple bargaining model with limited inter-player transfers. Poor functioning of the power sector leads to reduced pumping and a water supply constraint. Simulations show that power supply reform can significantly increase farm yields, and be financed out of increased farm profits.     

Is Marriage Poisonous? Are Relationships Taxing? An Analysis of the Male Marital Wage Differential in Denmark

Differences in the pattern of marriage, cohabitation, childbirth, and intrahousehold specialization between the United States and Denmark, as well as a rich, register-based panel sample of about 35,000 young Danish men, are exploited to shed light on the nature of the male marital wage differential. The results indicate that failing to control for cohabitation can seriously bias estimates of the marital wage differential, that marriage is a more selective state than cohabitation, and that specialization may explain some of the marital wage differential in the United States but not in Denmark. In Denmark, by contrast, there is evidence that fatherhood has a significant impact on earnings.
