Swiss watch cycles: Evidence of corruption during leadership transition in China

This paper presents evidence of corruption during China's leadership transitions when governmental positions are open for competition. The import value of luxury watches, a popular medium for corrupt exchanges, peaked during regular leadership transitions in 1996–97, 2001–02, and 2006–07. However, imports of nonluxury watches and other luxury items unpopular for corrupt exchanges did not exhibit the same cycle. Nor did imports of luxury watches increase in Hong Kong, Singapore, or the US. During the leadership transition of 2011–12, since wearing a conspicuous luxury watch was by then likely to be exposed on social media and trigger an anti-corruption investigation, this “Swiss watch cycle” vanished.     

An endogenous policy model of hierarchical government

Endogenous policy models usually neglect that government policies are frequently the result of decisions taken at different tiers by different agents, each enjoying some degree of autonomy. In this paper, policies are the outcome of the choices made by two agents within a hierarchy. A legislator decides on the budget to be successively spent by a bureaucrat. Both agents are lobbied by one or two interest groups. The combination of sequential decisionmaking and lobbying implies that the interaction between the agent at one tier and the interest group(s) depends on the exchange between the same interest group(s) and the agent at the other tier. Our results concerning multi-tier lobbying and legislatorial oversight substantially qualify the conventional wisdom related to one-tier lobbying. In particular, the reaction of the legislator to lobbying at the bureaucratic tier may make lobbying wasteful even when there is no competition from other lobbies. Moreover, the legislator benefits from lobbying only when there is competition between interest groups at the upper tier. It is also shown that competition for influence at the bureaucratic tier may work as a perfect substitute for legislatorial oversight. Extensions of the model indicate its usefulness for the analysis of decisionmaking in other multilevel governance structures, like federations or firms.     

Committing to transparency to resist corruption

This paper studies firms' incentives to commit to transparent behavior in a competitive procedure modeled as an asymmetric information beauty contest managed by a corrupt agent. In his evaluation of firms' offers for a public contract the agent has some discretion to favor a firm in exchange for a bribe. While unilateral commitment to transparency is never incentive compatible, under some circumstances a voluntary but conditional commitment mechanism can eliminate corruption. A low quality firm may prefer not to commit only when the agent's discretion is strong and the market's profitability is small. In that situation, the high quality firms commit when commitment decisions are kept secret, but some conditions on firms' beliefs are required when commitment decisions are publicly announced. A mechanism combining both conditionality and a reward (a transparent selection advantage that needs not be large) allows complete elimination of corruption.     

Corruption and competition in procurement

We consider a procurement problem in which the procurement agent is supposed to allocate the realization of a project according to a competitive mechanism that values bids in terms of the proposed price and quality. Potential bidders have private information about their production costs. Since the procurement agent is also in charge of verifying delivered quality, in exchange for a bribe, he can allow an arbitrary firm to be awarded the realization of the project and to produce a quality level lower than that announced. We compute equilibrium corruption and we study the impact on corruption of the competitiveness of the environment, and in particular of: (i) an increase in the number of potential suppliers of the good or service to be procured, and (ii) an increase of competition in the market for procurement agents. We identify the effects that influence equilibrium corruption and show that, contrary to conventional wisdom, corruption may well be increasing in competition.     

Interlinkage and Generous Tit‐for‐Tat Strategy

We investigate an infinitely‐repeated prisoners' dilemma with imperfect monitoring and consider the possibility that the interlinkage of the players' distinct activities enhances implicit collusion. We show a necessary and sufficient condition for the existence of a generous tit‐for‐tat Nash equilibrium. Such an equilibrium, if it exists, is unique. This equilibrium achieves approximate efficiency when monitoring is almost perfect, where the discount factors are fixed.     

Decentralizing antipoverty program delivery in developing countries

We study the effects on accountability in government service delivery of decentralizing administration of an antipoverty program. While governments at both central and local levels are vulnerable to antipoor policy biases owing to political capture, centralized delivery systems are additionally prone to bureaucratic corruption, owing to problems in monitoring bureaucratic performance. Decentralizing the delivery system promotes cost-effectiveness and improves intraregional targeting at low program scales. But interregional targeting may deteriorate, as central grants to high-poverty regions shrink, owing to high capture of local governments by local elites in such regions.     

Are elections debt brakes? Evidence from French municipalities

We show that voters are fiscal conservatives, although in the long run only: while the average (over the mandate) level of debt has a negative impact on the probability of reelection, pre-election debt accumulation by incumbents increases their probability of reelection. As the negative impact becomes larger as the debt level becomes higher, it compensates for the short run effect. Elections thus appear as a disciplining device, even if a weak one.     

Deeds or words? The local influence of anti-immigrant parties on foreigners’ flows

We investigate the influence of anti-immigrant parties on foreigners' location choices. Considering Italian municipal elections from 2000 to 2018, we create a comprehensive database that includes a classification of the anti-/pro-immigration axis of leading political parties based on specialists' assessments. Adopting a bias-corrected regression discontinuity design, we find that the election of a mayor supported by an anti-immigrant coalition significantly affects immigrants' location choices only when considering the most recent years. This finding is not driven by the enactment of policies against immigrants but by an ‘inhospitality effect’, which has become stronger over time due to the exacerbation of political propaganda. Therefore, foreigners' flows are influenced by the local political environment only when immigration is central to the political debate.     

A belief-based approach to the repeated prisoners' dilemma with asymmetric private monitoring

This paper extends the belief-based approach to the repeated prisoners' dilemma with asymmetric private monitoring. We first find that the previous belief-based techniques [T. Sekiguchi, Efficiency in repeated prisoners' dilemma with private monitoring, J. Econ. Theory 76 (1997) 345-361; V. Bhaskar, I. Obara, Belief-based equilibria in the repeated prisoners' dilemma with private monitoring, J. Econ. Theory 102 (2002) 40-69] cannot succeed when players' private monitoring technologies are sufficiently different. We then modify the previous belief-based approach by letting the player with smaller observation errors always randomize between cooperate and defect along the cooperative path of the play. We show that with vanishing observation errors, efficiency and a folk theorem can be approximated using our modified belief-based strategies.     

The Nash-threats folk theorem with communication and approximate common knowledge in two player games

We show that the use of communications to coordinate equilibria generates a Nash-threats folk theorem in two-player games with “almost public” information. The results generalize to the n-person case. However, the two-person case is more difficult because it is not possible to sustain equilibria by comparing the reports of different players, and using these “third parties” to effectively enforce contracts.
