The Demand for Money in Brunei

Based on data for the 1974–95 period this paper estimates demand for narrow money and broad money in Brunei using the error-correction specification. Short-run and long-run elasticities are estimated with respect to real income, interest rate, expected price level and liquidity. Narrow money is quite responsive to changes in real income and interest rate in both the short and long terms. Broad money is income inelastic regardless of the time horizon, however, it is interest inelastic in the short run but interest elastic in the long run. Price elasticity of money demand is negligible in the short run but quite significant in the long run. Changes in the proportion of commercial bank assets placed in foreign money markets do not seem to affect demand for narrow money but their effect on the demand for broad money is both direct and significant.     

Sport as Business

There is both a popular and academic literature suggesting thatowners of sports teams do not profit maximize. The alternativeformulation entails either win or utility maximization, usuallysubject to a break-even constraint. Another line of economicanalysis holds that team owners do fundamentally profit maximizeor that profit maximization provides a useful benchmark againstwhich to assess actual performance. There has been some empiricalwork attempting to decipher the true objective function of teamowners. These results are inconclusive. Objective functions,however, remain important because they affect both owner behaviourand league performance. In practice, owners' objectives varyby team, league, and country and are strongly affected by howthe team relates to an owner's other assets. The next task formodelling the behaviour and performance of sports leagues isto take fuller account of the diversity of ownership objectiveswithin a given league.     

Sport and Gambling

We review the relationships between gambling and sport. Britishsports and sports infrastructure have benefited considerablyfrom funding through the National Lottery. We argue that thereis an implicit sports tax on lottery products and that thispolicy may be neither efficient nor equitable. We suggest thatfurther research, employing contingent valuation methodology,would be required before any firm conclusion could be made overwhether the spending facilitated by the tax represents an efficientallocation of resources. Betting on events and outcomes in sport,especially team sports, has become a high-growth sector; weexplore the potential for sports to capture some of this bettorspending and discuss associated public-policy issues. Whilesport may extract revenue from betting, there are also costs.We focus especially on betting corruption in sports, developingan expected utility framework to show where the risk of corruptionis most likely to arise and what regulatory options are opento sports governing bodies and government.     

Broadcasting and Sport

The broadcasting of sport is heavily regulated. Our main findingis that common trends, and differences, in the quality, quantity,and price of televised sport across Europe and USA cannot beadequately explained without reference to policy interventionsby national and supranational government, and by competitionand regulatory authorities. These interventions have a significantimpact on the organization and governance of sports, as wellas the structure of broadcasting markets and the conduct ofbroadcasting companies. Foreclosure of broadcasting marketsthrough exclusive, long-term contracts, bundling and verticalintegration, access of viewers to major sporting events, andcollective selling stand out as the most significant policyissues. We conclude by noting a number of policy implications.     

United States Demand for Indonesian Plywood 1

Indonesia's exports of plywood are the largest in the world and a leading source of foreign exchange earnings. Although the industry's growth has been rapid, several studies indicate that it has been subsidised both directly and indirectly. What are the prospects for Indonesia to offset these subsidies by raising plywood prices as its share of key import markets grows? This paper sheds light on this question by analyzing econometrically the United States' imports of Indonesian plywood from July 1979 to December 1986, using a monthly import demand model. The results suggest that Indonesia's rapid expansion into the US plywood market has been due primarily to its low plywood prices, and that attempts to raise prices relative to those of competing export regions would result in significant reductions in market share.     

Structural Changes in the Demand for Labor

This paper investigates why labor demand has shifted away from low-skilled toward high-skilled labor in The Netherlands. We focus on the role of changes in relative wages and technological progress. A flexible functional form, proposed by Diewert and Wales, the Symmetric Generalized McFadden cost function, is estimated for the exposed and sheltered sectors. The estimates are based on time-series data for the period 1972–1993, which recently became available. Labor-saving technological change explains most of the displacement of low-skilled workers. The computed elasticities suggest that substitution between labor as a whole and capital is small. However, substitution plays a modest role in the shift from low-skilled toward high-skilled labor, especially in the sheltered sector. Skill-capital complementarity seems relevant in both sectors.

Contest Theory and Sport

Contrary to most sports fans economists tend to view tournamentsnot only as a mechanism to identify the most able and most talentedathlete(s) but also as an instrument to increase the athletes'effort levels by designing an adequate compensation system thattakes into account the specificities of the contest under consideration.The paper proceeds in two different steps: First, it reviewsthe available evidence on sports contests and identifies somepuzzles that have not yet been resolved in the literature (theempirical separation of selection and incentive effects andthe impact of incentive pay in team settings). Second, it addressesthese puzzles and offers some new evidence supporting the basicassumptions offered by economic theory.     

有效推进需求侧管理的政策建议

面临疫情大流行带来的国际格局变化,以及供需双侧发展不平衡等发展新趋势,需要我们在构建"双循环"新发展格局过程中,除了要继续做好供给侧结构性改革以外,也要注重需求侧管理.需求侧管理要以有效扩大国内需求,推动消费结构升级,优化产品供给质量,构建更高水平开放型新体制,构建全球利益共同体等为重点,着力提高中等消费群体比重、促进消费升级,激发城乡居民消费意愿、优化内需结构,以供给创造需求、以投资撬动消费,推动更高水平开放,使我国经济更好地循环畅通.     

开发区亟待构建自主创新体系

开发区是我国发展集群经济、推动技术进步的重要载体,在电子信息、现代通信、生物医药、新材料等新兴领域培育出了一批具有自主知识产权的大企业,如联想、华为、方正等;同时,众多机制灵活的科技型中小企业在园区内也得到了长足发展。随着我国开发区经济的高速发展,开发区已基本完成“一次创业”的任务,目前正在向“二次创业”阶段转型。开发区的“一次创业”主要以园区空间规划与扩张、产业布局、引进企业为主,而“二次创业”则把关注点更多放在完善上下游产业链、构建园区的创新体系上。

Adverse Selection and the Demand for Supplementary Dental Insurance

In 1995 dental services were excluded from the compulsory health insurance package that covers the families of all Dutch employees in the market sector with incomes below a certain threshold. People had to choose between no insurance and supplementary insurance. The exclusion of dental services was unexpected and was accompanied by a generous acceptance policy and almost uniform premiums. Due to these features the exclusion constitutes a natural experiment to investigate whether customers with poorer teeth conditions are more likely to buy insurance. This is a key condition for adverse selection to matter. The empirical results show that adverse selection indeed occurs; individuals with poor teeth condition are more likely to choose insurance. The same holds for customers with more frequent visits in the past. Differences in prices play some role, whereas differences in income do not.
