Procurement favouritism and technology adoption

It is well known that the design of cost minimizing procurement rules for the selection of a contractor among distinct technological groups requires the favouritism of inefficient firms. In this paper, I show that, if technology adoption is non-contractible, these policies will also provide optimal incentives for the inefficient firms to adopt more efficient technologies.     

The impact of public information on bidding in highway procurement auctions

A number of papers in the theoretical auction literature show that the release of information regarding the seller's valuation of an item can cause bidders to bid more aggressively. This widely accepted result in auction theory remains largely untested in the empirical literature. Recent theoretical work has also shown that this effect can be more pronounced in auctions with larger common cost uncertainty. We examine the impact of a policy change by the Oklahoma Department of Transportation that led to the release of the state's internal estimate of the costs to complete highway construction projects. We perform a differences-in-differences analysis comparing bidding in Texas, a state that had a uniform policy of revealing the same information all throughout the period of analysis, to bidding in Oklahoma. Our results show that, in comparison to Texas auctions, the average bid in Oklahoma fell after the change in engineers’ cost estimate (ECE) policy. This decline in bids was even larger for projects where the common uncertainty in costs is greater. Moreover, the within-auction standard deviation of bids fell after the change in ECE policy with the most significant decline observed again in projects with greater common cost uncertainty.     

Multi-attribute procurement auctions with risk averse suppliers

We analyze multi-attribute procurement auctions with risk-averse suppliers. As the number of suppliers increases or the suppliers become more risk-averse, the equilibrium bidding price decreases under the first-score auction but remains the same under the second-score auction. A buyer prefers the first-score auction.     

Competition among auctioneers in large markets

We analyse a multistage game of competition among auctioneers. First, the auctioneers commit to some reserve prices; second, the bidders enter one auction, if any; and finally, the auctions take place. We show that for any finite set of feasible reserve prices, each auctioneer announces a reserve price equal to his production cost if the numbers of auctioneers and bidders are sufficiently large, though finite. Our result supports the idea that optimal auctions may be quite simple. Our model also confirms previous results for some “limit” versions of the model by McAfee (Econometrica 61 (1993) 1281-1312), Peters (Rev. Econ. Stud. 64 (1997) 97-123), and Peters and Severinov (J. Econ. Theory 75 (1997) 141-179).     

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.     

Competition in bureaucracy and corruption

This paper studies the consequences of introducing competition between bureaucrats. Firms are supposed to invest into eliminating negative externalities of production, while bureaucrats administer the process by issuing licences. Some bureaucrats are corrupt, that is, they issue a licence to any firm in exchange for a bribe. The competition regime is found to create more ex ante incentives for firms to invest, while the monopoly regime is better at implementing ex post allocation, that is, distributing the licences given the firms' investment decisions. Additional results on the effect of punishments and bureaucrats' rotation are provided.     

Snow removal auctions in Montreal: costs, informational rents, and procurement management

Abstract.  Using semi-parametric and non-parametric estimation techniques, we infer cost distributions and informational rents from 457 bids for snow removal contracts offered for tender by the City of Montreal between 1990 and 1998. Bids and costs have decreased over the sample period, while rents remained relatively constant. The City deserves credit for these results, as it has succeeded in exploiting economies of scale and triggering innovations while maintaining competition. Further, it has been successful in adjusting its reserve prices to keep up with the decreasing cost of snow removal.     

Tax distortions in Sweden and the United States

We calculate the welfare costs of distortionary taxation (including inflation) in models calibrated for the United States and Sweden. The welfare costs are calculated using comparative steady state as well as dynamic analysis, where we take the costs of transition from the distorted to the optimal steady state into account. We also calculate the welfare costs of adding stochastic fluctuations. Our main finding is that the total welfare costs of the distortionary taxes including the distortionary effects of inflation are about five times higher in Sweden than in the United States. Meanwhile, stochastic fluctuations in policy turn out to have a relatively small impact on welfare.     

The relevance of private information in mechanism design

Recent results in mechanism design show that as long as agents have correlated private information and are sufficiently risk neutral, it is possible to design mechanisms that leave agents with arbitrarily small information rents. We show that these full-rent-extraction results hinge on the implicit assumption that the agents’ beliefs uniquely determine their preferences. We present an example of the voluntary provision of a public good in which this assumption is relaxed, and consequently, even in highly correlated environments, if agents’ beliefs do not uniquely determine their preferences, then the extraction of the agents’ entire information rents is impossible.     

How to win a decision in a confederation

This paper deals with collective decision making within a group of independent states. The right to choose the public policy is delegated from the central authority to one of the states through a bidding procedure among the group state members. We identify the following tradeoff: competition among states yields higher transfers to the central authority, but the outcome tends to be less efficient than what it is when states negotiate prior to the decision making process. We extend and illustrate the model by means of a public good game involving several heterogeneous states.     

Dynamic Costs of the Draft

Abstract. We propose a dynamic general‐equilibrium model with human capital accumulation to evaluate the economic consequences of compulsory services (such as military draft or social work). Our analysis identifies a so far ignored dynamic cost arising from distortions in time allocation over the life cycle. We provide conservative estimates for the excess burden that arises when the government relies on forced labor rather than on income taxation to finance public expenditures. Our results suggest that eliminating the draft could produce considerable dynamic gains, both in terms of GDP and lifetime utility.     

Autocratic governors in public procurement

The personal role of sub-national rulers is crucial for regional development in countries with weak institutions. This paper studies the impact of regional governors’ tenure in office and their local ties on procurement performance in Russia. To identify the causal effect, we construct instruments for governor’s tenure by exploiting the regional vote share of ruling party in past parliament elections. We find the evidence that governors who do not have pre-governing local ties in the region (outsiders) demonstrate predatory behaviour, compared to governors with local ties (insiders). Namely, governors-outsiders restrict the competition at awarding stage significantly more than governors-insiders. Moreover, for governors-outsiders this restriction becomes stronger with tenure in office, while governors-insiders do not demonstrate such negative tenure effect. We argue that this restriction of competition by governors-outsiders cannot be explained by the intention of better contracts execution: the delays in execution and the probability of contract termination either increase or keep stable with tenure for governors-outsiders and these outcomes decrease with tenure for governors-insiders.     

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.     

The taxation of trades in assets

When the asset market is incomplete, there typically exist taxes on trades in assets that are Pareto improving. This fiscal policy is anonymous, it is fully and correctly anticipated by traders, and it results in ex post Pareto optimal allocations; as such, it improves over previously proposed constrained interventions.     

“Almost” subsidy-free spatial pricing in a multi-dimensional setting

Consider a population of citizens uniformly spread over the entire plane. The population faces a problem of locating public facilities financed by its users, who face an idiosyncratic private access cost to the facility. We show that, under mild assumptions, an external intervention that covers a tiny portion of the facility cost is sufficient to guarantee secession-proofness or no cross-subsidization, where no group of individuals is charged more than the cost incurred if it had acted on its own. Moreover, we demonstrate that in this case the Rawlsian access pricing is the only mechanism that rules out secession threats.     

Competitive equilibria of economies with a continuum of consumers and aggregate shocks

This paper studies competitive equilibria of a production economy with aggregate productivity shocks. There is a continuum of consumers who face borrowing constraints and individual labor endowment shocks. The dynamic economy is described in terms of sequences of aggregate distributions. The existence of competitive equilibrium is proven and a recursive characterization is established. In particular, it is shown that for any competitive equilibrium, there is a payoff equivalent competitive equilibrium that is generated by a suitably defined recursive equilibrium.     

Transfers in a polarized country: bridging the gap between efficiency and stability

We consider a political economy model of country whose citizens have heterogeneous preferences for a national policy and some regions may contemplate a threat of secession. The country is efficient if its breakup into smaller countries leads to an aggregate utility loss. We show that in an efficient country whose citizens' preferences exhibit a high degree of polarization, a threat of secession cannot be eliminated without inter-regional transfers. We also demonstrate that if majority voting is used to determine the redistribution schemes within the country, then a high degree of polarization yields the full-compensation scheme as the unique political equilibrium.     

Competitive careers as a way to mediocracy

I show that in competitive careers based on individual performance the least productive individuals may have the highest probabilities to be promoted to top positions. These individuals have the lowest fall-back positions and, hence, the highest incentives to succeed in career contests. This detrimental incentive effect exists irrespective of whether effort and talent are substitutes or complements in the underlying contest-success function. However, in case of complements the incentive effect can be outweighed by a productivity effect that favors high effort choices by the more talented individuals. Switching from wages-attached-to-jobs to pay-for-performance at top career positions can be a solution to the mediocracy problem.     

Information in conflicts

We consider two-player contests for a prize of common but uncertain value. For settings where one player knows the value of the prize, while the other only knows its prior distribution, we give conditions for when the uninformed agent is ex ante strictly more likely to win the prize than is the informed agent. In the special case of a lottery contest, equilibrium expenditures are lower under asymmetric information than if either both agents are informed or neither agent is informed.     

Do people respond to tax incentives? An analysis of the Italian reform of the deductibility of home mortgage interests

Before 1992 mortgage interests in Italy were fully tax deductible up to 3500 Euro (7000 for two cosigners). In 1992-1994 the government implemented a series of tax reforms whose ultimate effect was to eliminate the relation between the after-tax mortgage rate and the marginal tax rate. Using data from the 1989-2002 Survey of Household Income and Wealth we test if the elimination of incentives has affected the sensitivity of the decision to borrow and the amount borrowed with respect to the marginal tax rate. Regression analysis and difference-in-differences estimates indicate that tax considerations have not affected the demand for mortgage debt, neither at the extensive nor intensive margin. These results are consistent with lack of financial information and credit rationing during the sample period.
