The paper analyzes situations, generalizing the duopoly problem, where two identical players are allowed with two control variables each, all of them linked through two non-strategic private constraints. Four dual equilibria are then obtained when each agent selects one leading variable to optimize and adjusts the other, and these equilibria are compared in a meta-game. For a simplified class of continuous games with linear constraints, it is shown that one symmetric dual equilibrium dominates the others and is the only perfect equilibrium of the metagame. The latter result holds locally for all quasi-concave utility functions and globally for all homogeneous ones, always keeping linear constraints. However, it is no longer valid in discrete games where the implicit constraints are not linear. Journal of Economic Literature Classification Numbers: C72, D43. 相似文献

Making Conditional Cash Transfer Programs More Efficient: Designing for Maximum Effect of the Conditionality 总被引:2,自引:0,他引:2
Conditional cash transfer programs are now used extensivelyto encourage poor parents to increase investments in their childrenshuman capital. These programs can be large and expensive, motivatinga quest for greater efficiency through increased impact of theprograms imposed conditions on human capital formation.This requires designing the programs targeting and calibrationrules specifically to achieve this result. Using data from theProgresa randomized experiment in Mexico, this article showsthat large efficiency gains can be achieved by taking into accounthow much the probability of a childs enrollment is affectedby a conditional transfer. Rules for targeting and calibrationcan be made easy to implement by selecting indicators that aresimple, observable, and verifiable and that cannot be manipulatedby beneficiaries. The Mexico case shows that these efficiencygains can be achieved without increasing inequality among poorhouseholds. 相似文献

The reforms of the banking sector in China conducted so far have been seeking to accomplish, simultaneously, two conflicting goals. On the one hand, the objective was to prepare Chinese banks for international competition and put them at the pace with the transformations observed in its overall economy. On the other, there is a social-driven agenda concerning employment and regional inequalities. Using principal component analysis, this article explores the impact of the ongoing reforms in the Chinese banking sector on the performance of individual banks. The results show that despite identical regulation, business practices can be dissimilar at the individual level. Taken collectively, the results also show the increasing influence of Western management standards in the Chinese banking sector. 相似文献

The electric utility industry is in transition but needs to move even faster if the country is to meet its emissions goals. The industry has historically moved cautiously, but policies and regulatory approaches must avoid unintentionally reinforcing the status quo. Incentive‐oriented policies and redesigned regulations must balance environmental sustainability with economic sustainability. The authors draw on well‐established corporate finance principles to guide more effective policies. Shareholder‐focused utility executives must make investments conditioned by three elements: (1) the return on equity the utility can expect to make on each project; (2) the investors' required return on equity capital for each project; and (3) the size of the investment. The well‐established economic value added (EVA) model can assist policy analysis: V=(r‐k)I; where V is the shareholder value created, r is the return on equity, k is the return investors require if they are to invest in the stock, and I is the scale of the project. Any new incremental V translates into higher stock prices. All three elements of their model (i.e., risk, return, and scale) require attention by regulators and policymakers to create value for shareholders. The authors show how the right state policies could create powerful incentives for shareholder focused utility executives to support such transitions. 相似文献

Hunger games: or how the Allied blockade in the First World War deprived German children of nutrition,and Allied food aid subsequently saved them 下载免费PDF全文
Mary Elisabeth Cox 《The Economic history review》2015,68(2):600-631
At the onset of the First World War, Germany was subject to a shipping embargo by the Allied forces. Ostensibly military in nature, the blockade prevented not only armaments but also food and fertilizers from entering Germany. The impact of that blockade on civilian populations has been debated ever since. Germans protested that the Allies had wielded hunger as a weapon against women and children with devastating results, a claim that was hotly denied by the Allies. The impact of what the Germans termed the Hungerblockade on childhood nutrition can now be assessed using a newly discovered dataset based on heights and weights of nearly 600,000 German schoolchildren measured between 1914 and 1924. Statistical analysis reveals a grim truth: German children suffered severe malnutrition due to the blockade. Social class impacted risk of deprivation, with working‐class children suffering the most. Surprisingly, they were the quickest to recover after the war. Their rescue was fuelled by massive food aid organized by the former enemies of Germany, and delivered cooperatively with both government and civil society. The ability of former belligerents to work together after an exceptionally bitter war to feed impoverished children may hold hope for the future. 相似文献

Diverse instruments have been used to encourage developing agriculture. In the process, billions of dollars have been spent on providing incentives to peasants. Given scarce resources, an important concern has been the issue of what policy instruments to emphasize. In this regard, useful policy information can be gleaned from the role of expected profits (revenue and input prices), assets (irrigation and infrastructure), and relevant risks, in evoking peasant response. Using panel data for the period 1967/1968 to 1999/2000 pertaining to seven major Indian cash crops cultivated across 14 major states, we find strong evidence of a differential producer response in the post‐liberalization phase, although the important variables per se are much the same. Our results suggest that the preferred policy ought to emphasize availability of irrigation, affordable fertilizer, and rural infrastructure, rather than incessant increases in output prices. 相似文献
