商业贿赂成因与治理的经济学分析

垄断为商业贿赂的产生和蔓延创造了条件,特别是供求失衡和信息不对称的存在为经营者进行商业贿赂带来了动力。虽然我国近年来更加重视和加强了对商业贿赂的治理,但在成本约束和信息不对称的作用下,单纯依靠政府的监管来治理商业贿赂成本高昂且效果有限。所以要想有效治理商业贿赂,我们就要从商业贿赂的成因出发,瓦解其滋生的环境,在加强政府监管的同时进一步完善法律规制,并借助全社会力量构筑全方位的商业贿赂治理体系。     

Asymmetric Punishment as an Instrument of Corruption Control

The control of bribery is a policy objective in many developing countries. It has been argued that asymmetric punishments could reduce bribery by incentivizing whistle‐blowing. This paper investigates the role played by asymmetric punishment in a setting where bribe size is determined by Nash bargaining, detection is costly, and detection rates are set endogenously. First, if whistle‐blowing is infeasible, the symmetry properties of punishment are irrelevant to bribery deterrence but not to bribe size. Bribery disappears if expected penalties are sufficiently high; otherwise, bribe sizes rise as expected penalties rise. Second, when the bribe‐giver may whistle‐blow, a switch from symmetric to asymmetric punishment eliminates bribery only if whistle‐blowing is cheap and the stakes are low. When bribery persists, multiple bribe sizes could survive in equilibrium. The paper derives parameter values under which each of these outcomes occurs, and discusses implications for welfare and the design of policy.     

Who gets caught for corruption when corruption is pervasive? Evidence from China’s anti-bribery blacklist

This article empirically investigates why in a corruption-pervasive country only a minority of the firms get caught for bribery while the majority get away with it. By matching manufacturing firms to a blacklist of bribers in the healthcare sector of a province in China, we show that the government-led blacklisting is selective: while economically more visible firms are slightly more likely to be blacklisted, state-controlled firms are the most protected compared to their private and foreign competitors. Our finding points to the fact that a government can use regulations to impose its preferences when the rule of law is weak and the rule of government is strong.     

Trade liberalization,wilful credit defaults and bank bribery in a credit-constrained economy

The rising incidence of credit defaults may cause credit crunch. This affects the ability of firms to finance working capital and also fixed capital formation. Naturally, this is a major macroeconomic shock. This paper is an attempt to address the microeconomic foundation of such macroeconomic shock. We provide a theoretical framework to explain the economic rationale behind ‘wilful corporate defaults’ and ‘financial corruption’ in the specific context of trade liberalization. First, we model the behavioural aspects of wilful corporate defaulters and bank officials to determine the bank bribe rate as an outcome of the Nash bargaining process in a two-stage sequential move game. Based on the results of the partial equilibrium framework, we examine aspects of trade liberalization in an otherwise 2 × 2 general equilibrium framework. We also compare the efficacy of punishment strategies to economic incentives to deter credit defaults and banking sector corruption. Methodologically, our analytical model integrates finance capital distinctly from physical capital in Jonesian general equilibrium framework. Interestingly, our findings indicate that there exists a trade-off at equilibrium between curbing credit defaults and bribery. We also find that not all punishment strategies are equally effective at deterring credit defaults if general equilibrium interlinkage effects are carefully dealt with.     

How corruption hits people when they are down

Using Peruvian data, I show that victims of misfortune, particularly crime victims, are much more likely than non-victims to bribe public officials. Misfortune increases victims' demand for public services, raising bribery indirectly, and also increases victims' propensity to bribe certain officials conditional on using them, possibly because victims are desperate, vulnerable, or demanding services particularly prone to corruption. The effect is strongest for bribery of the police, where the increase in bribery comes principally through increased use of the police. For the judiciary the effect is also strong, and for some misfortunes is composed equally of an increase in use and an increase in bribery conditional on use. The expense and disutility of bribing thus compound the misery brought by misfortune.

The effects of externalities and framing on bribery in a petty corruption experiment

Using a simple one-shot bribery game simulating petty corruption exchanges, we find evidence of a negative externality effect and a framing effect. When the losses suffered by third parties due to a bribe being offered and accepted are high and the game is presented as a petty corruption scenario instead of in abstract terms bribes are less likely to be offered. Higher negative externalities are also associated with less bribe acceptance. However, framing has no effect on bribe acceptance, indicating that the issue of artificiality may be of particular importance in bribery experiments.     

Decentralized Bribery and Market Participation

I propose a bribery model that examines decentralized bureaucratic decision‐making. There are multiple stable equilibria. High levels of bribery reduce an economy's productivity because corruption suppresses small business, and reduces the total graft, even though the size of an individual bribe might increase. Decentralization prevents movement towards a Pareto‐dominant equilibrium. Anticorruption efforts, even temporary ones, might be useful to improve participation, if they lower the bribe levels demanded and thus encourage small businesses to participate.     

Is corruption a greater burden for registered MSEs? Evidence from Zambia

If corrupt bureaucrats target registered firms, then corruption may discourage registration. Using data from a survey of 4,801 micro and small enterprises (MSEs) in Zambia, this paper looks at whether corruption is a more or less serious problem for registered MSEs. Consistent with earlier studies, the results suggest registered MSEs are more concerned about corruption than unregistered firms are. The paper also proposes two reasons why corruption might affect registered MSEs differently than it affects unregistered firms. We first suggest that registered firms might meet with government officials more often than unregistered firms, giving corrupt officials more opportunities to demand bribes from them, but we also suggest that registered firms might be less vulnerable when officials demand bribes because they are more able to complain about bribe demands. This could offset registered firms' disadvantage because of more frequent meetings. The evidence supports the first, but not the second, hypothesis. Registered firms were more likely to meet with government officials but were not consistently less likely to pay bribes when they did meet with them.     

Are corruption and taxation really harmful to growth? Firm level evidence

Exploiting a unique data set containing information on the estimated bribe payments of Ugandan firms, we study the relationship between bribery payments, taxes and firm growth. Using industry-location averages to circumvent potential problems of endogeneity and measurement errors, we find that both the rate of taxation and bribery are negatively correlated with firm growth. A one-percentage point increase in the bribery rate is associated with a reduction in firm growth of three percentage points, an effect that is about three times greater than that of taxation. This provides some validation for firm-level theories of corruption which posit that corruption retards the development process to an even greater extent than taxation.     

Bribery and firm survival in Vietnam: Moderating effects of market competition,credit, and institutional constraints

This paper examines the relationship between bribery and firm survival when facing different levels of market competition, credit constraints, and other institutional limitations. Using panel data from surveys of small- and medium-sized enterprises in Vietnam over a 10-year period and a semi-parametric Cox proportional hazards model approach, we provide empirical support for the “greasing-the-wheels” hypothesis of firm survival. Effects are found to be more pronounced for formally registered and larger firms, explained by their greater bargaining power vis-à-vis public officials. Moreover, bribery as a “risk-of-exit” reducing strategy is found only for firms not institutionally or financially constrained and for firms operating in sectors with low levels of competition.     

The Determinants of Firm Performance and Bribery: Evidence from Manufacturing Firms in Nigeria

This paper uses ordinary least squares with firm effects and Probit regression models to investigate the determinants of firm performance and the likelihood of firms to pay bribes. Results for the manufacturing firms in Nigeria show that skilled workforce, exports, foreign ownership and capital investment influence firm performance. Conversely, poor electricity delivery and difficulty obtaining finance impede firm performance. Total sales and time spent dealing with government regulations increase the likelihood of firms to pay bribes. Surprisingly, foreign firms are as much likely to pay bribes as domestic firms. Policy implications from the findings are important considering that the manufacturing sector assumes an important role in the Lewis theory of economic development.     

On corruption,bribes and the exchange of favors

This paper investigates how the availability of alternative forms of bribe payments, on top of money, may facilitate corruption. There are two bribe payment technologies and a Corruptor and a Receiver must agree on the value and on the technology of the bribe. The paper infers which form of payment can be used by analyzing probabilities of punishment, bargaining powers of agents, and relative efficiency of the two different technologies. By assumption, monetary payments have distinct efficiency than do non-monetary favors. If the Receiver has a sufficiently high utility for payments using a particular technology, then only bribes paid via this technology are feasible. There is also a range of intermediate cases where monetary bribery is used if and only if the relative bargaining power of the Receiver is sufficiently large compared to that of the Corruptor.     

Procurement auctions with ex-ante endogenous bribery

Corruption is a prevalent phenomenon in various procurement auctions. This paper explores a pattern of bribery between an auctioneer and a favored bidder, and also investigates the regulation scheme of buyer. In the model, the favored bidder is allowed to submit two bids simultaneously with the advantageous one to be announced; auctioneer decides the share of the difference between two bids which is the bribe transfer. The analysis shows that, the favored bidder does not participate in the corruption if his cost exceeds a threshold; otherwise he submits two bids whose difference is decreasing in the share. The corruption benefits both the auctioneer and the favored bidder but harms other bidders. The bribery endogenously leads to allocation inefficiency with a probability decreasing in the bribe share. Specifically, with two uniformly distributed bidders, we examine how the auctioneer optimizes the bribe share and how the buyer regulates the corruption. We find that, by driving the auctioneer to charge a higher bribe share that is less attractive for the favored bidder, severer regulation tends to reduce the probability of corruption. A buyer who adopts extremely severe regulation can exclude the corruption and achieve maximum social welfare, while a buyer who aims to maximize his own profit should tolerate some degree of the corruption.     

Former Communist party membership and bribery in the post-socialist countries

We study the effect of former Communist party membership on paying bribes to public officials and motivations for bribery, 25 years after the fall of communist rule. Data come from a large representative survey, conducted in post-socialist countries in 2015/16. To deal with endogeneity, we instrument party membership with information on whether family members were affected by the Second World War. Instrumental variable results suggest that links to the former Communist party increase the likelihood of paying bribes today; this result applies to the former party members as well as their children and relatives. Among bribe payers, people with the party links are more likely to offer bribes as well as think that bribe payments are expected. Overall, our findings suggest that the proclivity to corruption of the former Communist party members has been transmitted through family and thus sustained over time, contributing to corruption decades after the demise of the Socialist bloc.     

Are new states more corrupt? Expert opinions versus firms’ experiences

We find that new states are perceived to be more corrupt even though businesses do not report more bribery in newer states. This is suggestive of an unearned, and likely high, reputational cost to being a new state. These findings hold over a number of specifications that include additional economic, historical and geographic controls.     

Economics of public good provision: auditing, outsourcing, and bribery

Abstract .  This study investigates a government's contracting decision to audit or outsource the provision of a public good given a potential hidden bribe and information asymmetries. The key findings are the following. First, the bribe and price of the public good are increasing in the corruptibility of the department. Second, the bribe is decreasing in the firm's bargaining power. Third, a bribery equilibrium exists when the department's corruptibility is sufficiently high given the firm's bargaining power. A bribe involves extortion or a compensatory payment depending on the department's corruptibility. Only a compensatory bribe affects the department's contracting decision.     

Taxation and corruption: theory and firm-level evidence from Uganda

This article develops a simple framework to analyse the negotiation over bribe and tax payments during the tax collection process. We show that the larger the bribe a firm offers to a tax collector, the larger the tax rebate it gets. More particularly, we show that the negotiation over bribe and tax payments hinges on four other factors: firms’ official liabilities, detection, firms’ negotiation power and red tape costs imposed on firms. Some of the predictions from the theoretical model are tested using firm-level data from Uganda. We find that bribe and tax payments are inversely related, thereby supporting the hypothesis of a negotiation taking place between firms and tax collectors. In particular, a 1% point increase in average bribe payments per employee is associated with a 7% point reduction in average amount of tax payments per employee. Results are robust to various instruments dealing with the endogenous relationship between bribes and taxes.     

Impact of firm heterogeneity on direct and spillover effects of FDI: Micro-evidence from ten transition countries

This paper presents a comparative study of the importance of direct technology transfer and spillovers through FDI on a set of 10 transition countries, using a common methodology and appropriate methods to account for selection and simultaneity correction. This paper considers by far the largest firm level dataset (more than 90,000 firms) used by any study on the spillover effects of FDI. The main novelty of the paper is the explicit control for various sources of firm heterogeneity when accounting for different effects of FDI on firm performance. This work shows that the heterogeneity of firms in terms of absorptive capacity, size, productivity and technology levels affect the results. Controlling for these variables leads to some interesting results, which contrast with the previous empirical work in the field. We find that horizontal spillovers have become increasingly important over the last decade, and they may even become more important than vertical spillovers. Positive horizontal spillovers are equally distributed across size classes of firms, while negative horizontal spillovers seem to be more likely to accrue to smaller firms. Moreover, positive horizontal spillovers seem more likely to be present in medium or high productivity firms with higher absorptive capacities, while negative horizontal spillovers are more likely to affect low to medium productivity firms. These findings suggest that both direct effects from foreign ownership as well as the spillovers from foreign firms substantially depend on the absorptive capacity and productivity level of individual firms. In addition, these results show that foreign presence may also affect smaller firms to a larger extent than larger firms, but this impact may be in either direction.     

How credit-constrained are firms in Turkey? A survey-based analysis

We study the factors related to the financing of firms in Turkey, using the Business Environment and Enterprise Performance Survey (BEEPS). Based on the survey responses of the firms, we calculate the ratio of credit-constrained firms in Turkey and run a logistic regression to investigate the factors explaining the firms’ access to credit. Estimation results show that the likelihood of having access to credit increases with the firm size. Firms are more likely to access credit if they are being independently audited or they are exporters, and they are less likely to access credit if they have overdue payments.
