Competition and open source with perfect software compatibility

In this paper we study duopolistic competition between closed and open source software. Inspired by recent contributions on open source, we propose a two-stage game with perfect information and product differentiation, in which producers first set software quality and then determine prices (the price is zero for open source programs). We assume perfect software compatibility and model lock-in effects, a network externality component of software quality, and accumulation of experience in software use and implementation. In comparison to the monopolistic benchmark case, we argue that, in a duopoly created by the emergence of an open source program, the proprietary software producer will reduce its selling price if: (i) its network of users is larger than the open source network and its consumers are largely familiar with its program, (ii) it has a small network of unskilled consumers. On the other hand, the price of proprietary software will increase if its users form a large, but poorly-skilled network. Furthermore, we show that, in all of the above cases, the hedonic quality of proprietary software increases. Finally, by modeling experience accumulation processes through difference equations, we show that the ratio between the closed and open source programs’ opportunity costs for software learning and deployment plays a crucial role in shaping market outcomes. If open source software remains too complex and technical for unskilled or time-pressed users, a shared market solution, in which both programs are adopted, is likely to emerge. However, if opportunity costs in learning and understanding open source programs are particularly low, or at least equal to the opportunity costs of a closed-source program, then open source dominance emerges (i.e. markets tip to open source).     

Tax,credit constraints,and the big costs of small inflation

This paper develops a heterogeneous‐agent overlapping generations model that examines how the neutrality of the tax system with respect to inflation depends on the price elasticity of the housing supply. The model, which endogenises house prices and rents, and which incorporates detailed tax regulations and bank‐imposed credit constraints, shows (a) inflation has large effects on the tenure arrangements of young households irrespective of the housing supply elasticity; and (b) inflation can improve the welfare of some low income young households if the supply is sufficiently elastic. The welfare costs of inflation are reduced by taxing real rather than nominal interest.     

Federalism and horizontal equity across Switzerland and Germany: a new rationale for a decentralized fiscal structure

Higher wages in agglomerations often do not reflect an increase in purchasing power, because a high percentage of the wage increase has to be spend on housing. Thus, after housing is considered taxpayers may have identical disposable incomes, although gross as well as after-tax income may differ. This unequal treatment of taxpayers is due to the taxation of nominal incomes. If tax systems taxed income based on regionally adjusted purchasing power, horizontal equity would be assured. Since this is an unfeasible option, the differences could be corrected by allowing a deduction on housing costs. Given the large revenue losses, it seems unlikely that governments in OECD countries move to a system where rents are deductible in determining taxable income. Another alternative—taxation of potentially achievable income—is unfeasible due to political opposition. A final and less costly alternative is fiscal federalism. Granting autonomy to the lower levels of the government offers local governments the power to design the tax system in a way that reflects differences in living costs. Although this option does not necessarily imply that governments effectively design the tax schedule in that way, a comparison of Germany and Switzerland shows that governments are aware of these differences across regions. The paper concludes that granting tax autonomy to the lower tiers in Germany would make many citizens, especially in the Southern part, better off and would promote horizontal equity among German taxpayers.     

Socially optimal procurement with tight budgets and rationing

We investigate the behaviour of a social planner that secures the supply of a good, e.g. an environmental benefit, through contracting with private agents. While the social planner seeks to maximise net social benefits, she is also controlled with a fixed budget. Private agents are profit maximising and hold private information concerning their variable costs of production. They also have known fixed costs of contracting. We find that budget constraints and fixed costs change the optimal contract design in more than one way: the social planner minimises costs, rations high-cost contracts to reduce fixed costs and information rents, and distorts contracts for all agent types, including low-cost agents. We find that rationing improves social welfare. Also, even though social costs – including tax distortion – are explicitly taken into consideration, they do not affect the design of optimal contracts when budgets are tight. In those cases the budget constraint dominates the solution.     

Efficient Migration and Income Tax Competition

This paper examines the consequence of the brain drain for the income tax systems of the source and destination countries for the migration, if the two countries' policies are set noncooperatively by self–interested voters. It is assumed that the brain drain does increase the value of world output: workers with the highest income–earning ability are assumed to be more productive in one country than in another. There are costs to migration of these high–ability workers, costs that are less than the gain in the value of their production. However, for lower–ability workers, the gains in production in moving from the low–productivity country to the high–productivity country are assumed to be less than the migration costs. Voters in the high–productivity country want to capture rents from migrants. These voters are aware of the influence their tax policy has on people's migration decisions. Voters in the low–productivity country also behave strategically. I solve for the Nash equilibrium income tax rates. Increased mobility of highly skilled workers cannot decrease, and may increase, progressivity in the income tax system of the destination country, if migration actually occurs. Finally, the effects of transfers between countries on their income tax systems are examined. Redistribution between countries tends to lead to less redistribution within countries. If transfers between countries are set by a vote of all residents of both countries, then the transfer chosen will be the one that leads to the least progressive tax possible being chosen in each country.

网络产业收入监管激励问题研究

对具有自然垄断特性的网络产业,各国都对其收入实施严格的监管。而如何采取具有激励作用的收入监管,历来是经济学家研究的重点。对该方面进行的综述性研究表明,在不对称信息存在的情况下,采取基于成本的收入监管机制,监管机构不得不对低效率企业的产出进行扭曲,同时高效率企业获得信息租金;而采取基于价格的收入监管机制,在考虑了企业的努力程度时,低效率企业的努力程度将受到向下的扭曲,同时高效率企业获得信息租金。分析还表明,在基于价格的收入监管机制下,价格机制的选取和激励问题可以分开考虑。

Asymmetric information and contract design for payments for environmental services

In contractual relationships involving payments for environmental services, conservation buyers know less than landowners know about the costs of contractual compliance. Landowners in such circumstances use their private information as a source of market power to extract informational rents from conservation agents. Reducing informational rents is an important task for buyers of environmental services who wish to maximize the services obtained from their limited budgets. Reducing informational rents also mitigates concerns about the “additionality” of PES contracts because low-cost landowners are least likely to provide different levels of services in the absence of a contract. Paying low-cost landowners less thus makes resources available for contracts with higher opportunity cost landowners, who are more likely to provide substantially different levels of services in the absence of a contract. To reduce informational rents to landowners, conservation agents can take three approaches: (1) acquire information on observable landowner attributes that are correlated with compliance costs; (2) offer landowners a menu of screening contracts; and (3) allocate contracts through procurement auctions. Each approach differs in terms of its institutional, informational and technical complexity, as well as in its ability to reduce informational rents without distorting the level of environmental services provided. No single approach dominates in all environments. Current theory and empirical work provides practitioners with insights into the relative merits of each approach. However, more theoretical work and experimentation in the laboratory and the field are necessary before definitive conclusions about the superiority of one or more of these approaches can be drawn.     

Regulatory Entry Barriers,Rent Shifting and the Home Market Effect

This paper introduces regulatory entry barriers in a model of the home market effect. The entry barriers generate local rents that have unexpected but significant implications. First, the home market effect is magnified. Second, when countries are sufficiently unequal in size and rents are sufficiently large, symmetric reductions in trade costs reduce welfare in the small country. Third, entry barriers increase the large country's market size and, surprisingly, can increase its welfare. Fourth, a unilateral increase in trade protection shifts foreign rents to the home country. This rent‐shifting effect amplifies the standard production relocation motive for trade policy intervention.     

官员规模、公共品供给与社会收入差距:权力寻租的视角

官员规模、公共品供给效率以及社会收入差距是当下社会比较关注的问题,本文试图把三个问题纳入到一个故事框架下来分析和解释。生产的进行需要官员提供资源帮扶,这需要通过雇佣下级官员来做到;当私人利益进入上级官员的收益函数时,上级官员就会促使资源的供给"人为"稀缺来设租,从而便于下级官员从生产者处收取资源租金;而资源租金的收取使得下级官员的收益高于其外部选择权收益,从而增加了下级官员职位的竞争性,又由于上级官员对下级官员职位任命权的垄断,使上级官员从下级官员处收取职位租金。分析表明,权力的设租寻租行为是造成社会收入差距出现的一个重要原因;在一个能较好限制官员关注私人收益的社会中,官员规模较小、公共品供给效率较高且因权力寻租而造成的社会收入差距较小。     

Policy making and rent-dissipation: An experimental test

We present a transfer-seeking model of political economy that links the theory of Becker (1983) with Tullock-type models of politically contestable rents. In our model the size of the transfer is determined endogenously, and over-dissipation of rents is predicted even under conditions of risk-neutrality and perfect rationality. We implement an empirical test of this model by collecting behavioral data in a laboratory experiment. We confirm the existence of behavior that leads to over-dissipation of rents in games with both symmetric and asymmetric political power. To the extent that the transfer-seeking costs are social costs, our findings imply that the total costs of running government might be greatly underestimated if the value of the rent is used as a proxy for the rent-seeking cost. We also confirm the hypotheses that lowering the political power of one player can lead to smaller rent-seeking expenditures and to larger transfers Electronic Supplementary Material Supplementary material is available in the online version of this article at .

Oil,Laws, and Female Labor Force Participation

Despite the rapid rise of women’s education and the fall of their fertility rates in the Middle East and North Africa (MENA), female labor force participation (FLFP) rates remain low. This paper argues that oil and gas rents and Islamic family law jointly matter. Controlling for country and year fixed-effects in a long panel dataset, it shows that per capita oil and gas rents reduce FLFP rates in countries with Islamic family law more than others. The results are robust to econometric methodology and to controlling for the interaction of rents and all other time-constant factors that are common across the MENA region, such as culture, social norms, and institutions. Moreover, the results cannot be replicated by substituting historical plough use, a strong predictor of gender discrimination, in place of Islamic family law. Policy implications are discussed.     

Oil rents, corruption, and state stability: Evidence from panel data regressions

We examine the effects of oil rents on corruption and state stability exploiting the exogenous within-country variation of a new measure of oil rents for a panel of 30 oil-exporting countries during the period 1992–2005. We find that an increase in oil rents significantly increases corruption, significantly deteriorates political rights while at the same time leading to a significant improvement in civil liberties. We argue that these findings can be explained by the political elite having an incentive to extend civil liberties but reduce political rights in the presence of oil windfalls to evade redistribution and conflict. We support our argument documenting that there is a significant effect of oil rents on corruption in countries with a high share of state participation in oil production while no such link exists in countries where state participation in oil production is low.     

Sectoral systems of environmental innovation: An application to the French automotive industry

This article seeks to show how a sectoral system approach may contribute to the analysis of the determinants of environmental innovations. By using Malerba's [F. Malerba: Sectoral systems of innovation and production, Res. Policy Vol. 102, 845-859, (2002)] concept of sectoral system of innovation and production, we develop a sectoral framework based on three building blocks: technological regimes, demand conditions and environmental and innovation policy. Within this framework, the sectoral patterns of environmental innovation result from the interplay between these three blocks. The conceptual framework is applied to the case of the French automotive industry, with a specific focus on the development of low emission vehicles. The analysis shows how technological regime and demand conditions lead to technological inertia, and so to a strong persistence of the dominant design. Finally, environmental and innovative policy are considered in an integrated way, so that we can study how they influence technological regime and demand conditions, and in the meantime how they are conditioned by these two blocks.     

On the socially optimal density of coin and banknote series: Do production costs really matter?

By adding denominations to their coin and banknote series central banks can increase the efficiency of cash payments. In practice, however, they opt for a denominational structure with a relatively low density. The literature holds that this is because of the production costs involved. To test this proposition, we introduce a per-denomination fixed cost into the matching model of Lee et al. (2005) and parameterize the model with data on the production of US dollar banknotes. Our simulations demonstrate that central banks could increase the density of their currency systems beyond the observed level without the efficiency gains for transactors being dwarfed by the additional production costs for the central bank itself. This suggests that the explanation for the low density rather lies with costs incurred by consumers and merchants - and anticipated by central banks - that are not yet in any of the extant models.     

A Model of Inequality and Interest Group Politics

In this paper we examine inequality of process and inequality of outcomes in interest group politics. The model has interest groups that compete for rents in a non-cooperative game. It allows for a self-interested rent-setting political decision-maker, and democratic or popular pressure as a check on that self-interest. We consider differences in the effectiveness and pre-commitment abilities of interest groups. We show that: (i) the costs of influence activities may be highest when groups are relatively equal in their effectiveness; (ii) if social welfare incorporates enough concern for equity of outcomes, that ranking is reversed; (iii) depending on voter responsiveness to rent-setting, the political decision-maker may set rents to be higher or lower, when increases in inequality of effectiveness lower the unit costs of rent-seeking.     

Budget Cuts, Social Assistance and Voluntary Unemployment

The theory of optimal taxation has shown that bunching can be optimal under certain circumstances so that low–skilled agents are not offered any work incentives. Optimal bunching balances the marginal costs of voluntary unemployment and the marginal reduction in information rents for high–skilled workers. This paper demonstrates how the optimal scheme will change if the budget is cut. It shows that a tighter budget constraint will lead to more voluntary unemployment and less work incentives.     

Engineering solutions to software problems: Some institutional and social factors shaping change

Software is the core of information technology systems, the major factor i n system costs and the main source o f system malfunctions. The software development process is currently characterized as a labour-intmsive craft activity which has resisted automa- tion. Software engineering covers a set of approaches which are intended to address the long-standing twin problems of low productizlity in software development and the poor quality of software products. It encompasses a range of tools, methods and procedures which aim to assert a n engineering culture to displace existing ad hoc processes. Many governments have supported programmer of software engineering R&D. This article argues that the adoption of sotiware engineering is mediated and resisted by social, organizational, cultural and in~titutionat factors. These are identified and their implications discussed.
