SHADES OF BROWN AND GREEN: PARTY EFFECTS IN PROPORTIONAL ELECTION SYSTEMS

In proportional representation (PR) systems, political power is typically shared across several political parties. Many parties are small and focused on specific policies, such as environmental policy and immigration. Do these small parties matter for policy? I provide the first systematic evidence for this by developing the first regression discontinuity design tailored specifically for PR systems. With this method, which can be applied in all countries with PR systems, I estimate the causal effect of party representation on immigration policy, environmental policy and tax policy using data on Swedish municipalities. The results show that party representation has a large effect on the first two policies, but not on the tax policy.     

Joint Mail‐In Rebate Decisions in Supply Chains Under Demand Uncertainty

We study the joint decisions of offering mail‐in rebates (MIRs) in a single‐manufacturer–single‐retailer supply chain using a game theoretic framework. Either party can offer an MIR to the end consumer if it is in his best interest. The consumer demand is stochastic and depends on the product price and the amount of MIRs. When the retail price is exogenous, we show the existence of a unique Nash equilibrium under both additive and multiplicative demand functions and characterize it completely. We show that any of the following four scenarios can be the equilibrium: both parties offer MIR, only one party offers MIR, none offers MIR. When the retail price is a decision variable for the retailer and the rebate redemption rate increases with the amount of MIR, we once again prove the existence of a unique Nash equilibrium where both the retailer and the manufacturer offer MIRs. Using a numerical study, we show that the average post‐purchase price of the product is higher not only than the perceived pre‐purchase price but also than the newsvendor optimal price without an MIR. This implies that an MIR makes a product look cheaper while the consumers actually pay more on average.     

Altruism in Networks

We provide the first analysis of altruism in networks. Agents are embedded in a fixed network and care about the well‐being of their network neighbors. Depending on incomes, they may provide financial support to their poorer friends. We study the Nash equilibria of the resulting game of transfers. We show that equilibria maximize a concave potential function. We establish existence, uniqueness of equilibrium consumption, and generic uniqueness of equilibrium transfers. We characterize the geometry of the network of transfers and highlight the key role played by transfer intermediaries. We then study comparative statics. A positive income shock to an individual benefits all. For small changes in incomes, agents in a component of the network of transfers act as if they were organized in an income‐pooling community. A decrease in income inequality or expansion of the altruism network may increase consumption inequality.     

Identification and Estimation of a Discrete Game of Complete Information

We discuss the identification and estimation of discrete games of complete information. Following Bresnahan and Reiss (1990, 1991), a discrete game is a generalization of a standard discrete choice model where utility depends on the actions of other players. Using recent algorithms to compute all of the Nash equilibria to a game, we propose simulation‐based estimators for static, discrete games. We demonstrate that the model is identified under weak functional form assumptions using exclusion restrictions and an identification at infinity approach. Monte Carlo evidence demonstrates that the estimator can perform well in moderately sized samples. As an application, we study entry decisions by construction contractors to bid on highway projects in California. We find that an equilibrium is more likely to be observed if it maximizes joint profits, has a higher Nash product, uses mixed strategies, and is not Pareto dominated by another equilibrium.     

Competition for a Majority

We define the class of two‐player zero‐sum games with payoffs having mild discontinuities, which in applications typically stem from how ties are resolved. For such games, we establish sufficient conditions for existence of a value of the game, maximin and minimax strategies for the players, and a Nash equilibrium. If all discontinuities favor one player, then a value exists and that player has a maximin strategy. A property called payoff approachability implies existence of an equilibrium, and that the resulting value is invariant: games with the same payoffs at points of continuity have the same value and ɛ‐equilibria. For voting games in which two candidates propose policies and a candidate wins election if a weighted majority of voters prefer his proposed policy, we provide tie‐breaking rules and assumptions about voters' preferences sufficient to imply payoff approachability. These assumptions are satisfied by generic preferences if the dimension of the space of policies exceeds the number of voters; or with no dimensional restriction, if the electorate is sufficiently large. Each Colonel Blotto game is a special case in which each candidate allocates a resource among several constituencies and a candidate gets votes from those allocated more than his opponent offers; in this case, for simple‐majority rule we prove existence of an equilibrium with zero probability of ties.

On the Advantage of Quantity Leadership When Outsourcing Production to a Competitive Contract Manufacturer

This study investigates a supply chain comprising an original equipment manufacturer (OEM) and a contract manufacturer (CM), in which the CM acts as both upstream partner and downstream competitor to the OEM. The two parties can engage in one of three Cournot competition games: a simultaneous game, a sequential game with the OEM as the Stackelberg leader, and a sequential game with the CM as the Stackelberg leader. On the basis of these three basic games, this study investigates the two parties' Stackelberg leadership/followership decisions. When the outsourcing quantity and wholesale price are exogenously given, either party may prefer Stackelberg leadership or followership. For example, when the wholesale price or the proportion of production outsourced to the CM is lower than a threshold value, both parties prefer Stackelberg leadership and, consequently, play a simultaneous game in the consumer market. When the outsourcing quantity and wholesale price are decision variables, the competitive CM sets a wholesale price sufficiently low to allow both parties to coexist in the market, and the OEM outsources its entire production to this CM. This study also examines the impact of the supply chain parties' bargaining power on contract outcomes by considering a wholesale price that is determined via the generalized Nash bargaining scheme, finding a Stackelberg equilibrium to be sustained when the CM's degree of bargaining power is great and the non‐competitive CM's wholesale price is high.     

Public Financing of Education and Research in a Model of Endogenous Growth

We propose a two factor endogenous growth model in which the government intervenes in the economy by financing research and/or education. We allow technology in public production to be different from technology in private production, so that public spending has a direct effect on the rental prices of factors. We characterize both the unique balanced growth path and the transitional dynamics of the model showing the steady state equilibrium to be a saddle point. We also show that while income taxation is distortive, in general, a Pareto optimal outcome can be reached by means of a consumption tax in the decentralized setting.     

Improving Valuation Under Consumer Search: Implications for Pricing and Profits

There is a growing trend in the retail industry to improve customer experience. In this article, we study retailer‐initiated strategies to increase consumer valuation for a product under duopoly. In such a setting, it is possible that a consumer's valuation may be increased by one retailer; however, the consumer may decide to buy the product from the competitor. We consider a two‐stage game where retailers first decide whether to invest in improvements in customer valuation and then engage in price competition. We computationally explore the Nash equilibria in terms of both investment and pricing. We find that in the majority of cases retailers price in a manner to discourage their local customers to buy from the competitor. Next, we focus on the pricing game and theoretically characterize the pricing Nash equilibrium. We find that a retailer could overcome competitive effects by improving consumer valuation beyond a certain threshold. We also find that a retailer who does not invest could benefit from competition in situations where his competitor increases consumer valuation beyond a threshold. Finally, we explore through a computational study the Nash equilibria of the two‐stage game using an alternate model to establish the robustness of our findings.

Backward Induction Foundations of the Shapley Value

We present a noncooperative game model of coalitional bargaining, closely based on that of Gul (1989) but solvable by backward induction. In this game, Gul's condition of “value additivity” does not suffice to ensure the existence of a subgame perfect Nash equilibrium that supports the Shapley value, but a related condition—“no positive value‐externalities”—does. Multiple equilibria can arise only in the event of ties, and with a mild restriction on tie‐break rules these equilibria all support the Shapley value.

Grenzen und Erweiterungsmöglichkeiten der investitionsneutralen Besteuerung nach dem ökonomischen Gewinn

We analyse the the concept of economic income taxation with regard to investment neutrality and the ability to pay principle. We build a bridge between the sum of economic incomes, net present value and the sum of total cash flows. Further it is shown, that the use of economic income for the evaluation of tax systems is distorted by two effects, the interest effect and a so called time-window effect. As to mitigate these effects we propose to include the net present value in the tax base. We apply both concepts to the field of neutrality based effective tax rates on the one hand and we discuss their limits under realistic circumstances on the other hand. In both cases our concept provides at least better results than those achieved under the traditional economic income concept.     

Welche privaten Veräußerungsgewinne sollten besteuert werden?

This paper analyses for various corporate tax systems whether the capital gains tax distorts investment decisions and how tax effects could eventually be neutralized. In case of the disposal of shares between private investors the capital gains tax, the corporate tax and the income tax on dividends induce a triple taxation. On the contrary, distributing cash via share repurchases instead of paying out dividends can lower the tax burden in a classical corporate tax system and a shareholder relief system respectively. These findings necessitate the differentiation between share repurchases and other realizations of stocks in order to establish a neutral capital gains tax. While the capital gains taxation on transactions between private investors has to be reduced, the taxation of share repurchases must be matched with the respective dividend taxation.     

基于微分博弈的供应链质量协调研究

文章以一个制造商和一个供应商所构成的两级供应链为研究对象,应用微分博弈的方法分析了四种不同的质量管理博弈情形下,制造商和供应商的最优质量管理策略、收益和整条供应链的总收益。研究结果表明,当制造商和供应商的收益分配比满足一定条件时,从Nash非合作质量管理博弈情形,到弱激励Stackelberg博弈情形,再到强激励Stackelberg博弈情形,最后到合作质量管理博弈情形,对于制造商、供应商以及整个供应链系统来说都是一种帕累托改进。所以,合作质量管理博弈情形是供应链质量管理所追求的最理想的情形,为了有效促进该情形的实现,文章应用Nash讨价还价模型对该情形下合作双方关于供应链系统的剩余利润分配进行了分析。最后,在对一家电风扇制造商的供应链进行调查来获得仿真数据的基础上,通过算例分析验证了理论推导的结果。     

DO PARTIES MATTER FOR ECONOMIC OUTCOMES? A REGRESSION‐DISCONTINUITY APPROACH

A long‐standing issue in political economics is to what extent party control makes a difference in determining fiscal and economics policies. This question is very difficult to answer empirically because parties are not randomly selected to govern political entities. This article uses a regression‐discontinuity design, namely, party control changes discontinuously at 50% of the vote share, which can produce “near” experimental causal estimates of the effect of party control on economic outcomes. The method is applied to a large panel data set from Swedish local governments with a number of attractive features. The results show that there is an economically significant party effect: Left‐wing governments spend and tax 2–3% more than right‐wing governments. Left‐wing governments also have 7%lower unemployment rates, which is partly due to that left‐wing governments employ 4% more workers than right‐wing governments. (JEL: C21, D72, D78, H71, H72)     

Multiperson Bargaining and Strategic Complexity

We investigate the effect of introducing costs of complexity in the n‐person unanimity bargaining game. As is well‐known, in this game every individually rational allocation is sustainable as a Nash equilibrium (also as a subgame perfect equilibrium if players are sufficiently patient and if n & 2). Moreover, delays in agreement are also possible in such equilibria. By limiting ourselves to a plausible notion of complexity that captures length of memory, we find that the introduction of complexity costs (lexicographically with the standard payoffs) does not reduce the range of possible allocations but does limit the amount of delay that can occur in any agreement. In particular, we show that in any n‐player game, for any allocation z, an agreement on z at any period t can be sustained as a Nash equilibrium of the game with complexity costs if and only if t≤n. We use the limit on delay result to establish that, in equilibrium, the strategies implement stationary behavior. Finally, we also show that ‘noisy Nash equilibrium’ with complexity costs sustains only the unique stationary subgame perfect equilibrium allocation.     

The Bubble Game: An Experimental Study of Speculation

We propose a bubble game that involves sequential trading of an asset commonly known to be valueless. Because no trader is ever sure to be last in the market sequence, the game allows for a bubble at the Nash equilibrium when there is no cap on the maximum price. We run experiments both with and without a price cap. Structural estimation of behavioral game theory models suggests that quantal responses and analogy‐based expectations are important drivers of speculation.
