BIDS AND COSTS IN COMBINATORIAL AND NONCOMBINATORIAL PROCUREMENT AUCTIONS—EVIDENCE FROM PROCUREMENT OF PUBLIC CLEANING CONTRACTS

Combinatorial procurement auctions enable suppliers to pass their potential cost synergies on to the procuring entity and may therefore lead to lower costs and enhance efficiency. However, bidders might find it profitable to inflate their stand‐alone bids in order to favor their package bids. Using data from standard and combinatorial procurement auctions, we find that bids on individual contracts in simultaneous standard auctions without the option to submit package bids are significantly lower than the corresponding stand‐alone bids in combinatorial auctions. Further, no significant difference in procurer's cost as explained by auction format is found. (JEL D44, H57, L15)     

Interindustry Wage Differentials and Unobserved Ability: Siblings Evidence from Five Countries

We examine the role of unobserved ability in explaining interindustry wage differentials. By using data on brothers, we account for unmeasured abilities shared by siblings. The data came from four Nordic countries and the United States. In the Nordic countries, only a moderate proportion of the variability in industry wages can be attributed to unobserved ability, while unmeasured factors explain as much as half of the U.S. industry‐wage variation. Accounting for such differences, we show that the U.S. interindustry wage dispersion is similar with that in the Nordic countries.     

CORRUPTION AND POLITICAL AND ECONOMIC REFORMS: A STRUCTURAL BREAKS APPROACH

In this paper we look at the impact of broad policy reforms on the levels of corruption. We use a structural break approach to identify country-specific time periods in which significant shifts in corruption levels take place. We then correlate these times of change with a set of covariates with specific focus on the impact of democratization, and trade and equity market liberalization. We find robust support for the hypothesis that episodes of reduction in corruption levels tend to be correlated with democratization and equity market liberalization.     

Market Structure and Transaction Costs of Index CDSs

Despite regulatory efforts to promote all-to-all trading, the post–Dodd-Frank index credit default swap market remains two-tiered. Transaction costs are higher for dealer-to-client than interdealer trades, but the difference is explained by the higher, largely permanent, price impact of client trades. Most interdealer trades are liquidity motivated and executed via low-cost, low-immediacy trading protocols. Dealer-to-client trades are nonanonymous; they almost always improve upon contemporaneous executable interdealer quotes, and dealers appear to price discriminate based on the perceived price impact of trades. Our results suggest that the market structure is a consequence of the characteristics of client trades: relatively infrequent, large, and differentially informed.     

DOES INDIAN CASINO GAMBLING REDUCE STATE REVENUES? EVIDENCE FROM ARIZONA

Critics of Indian gaming contend that reservation casinos have a negative impact on state economies. This paper tests the hypothesis that the introduction of Indian casinos caused a structural change in the formation of Arizona state revenues. Data are from Maricopa County, the largest county in Arizona. Findings suggest that Indian casinos may divert funds from taxable to non-taxable sectors. The growth in tax revenue from non-gaming sectors of the economy has masked these displacement effects. However, given the trend toward increasing the proportion of state funds from sales taxes, a diminution in the rate of economic growth could have serious implications for future state budgets.     

Linear‐Rational Term Structure Models

We introduce the class of linear‐rational term structure models in which the state price density is modeled such that bond prices become linear‐rational functions of the factors. This class is highly tractable with several distinct advantages: (i) ensures nonnegative interest rates, (ii) easily accommodates unspanned factors affecting volatility and risk premiums, and (iii) admits semi‐analytical solutions to swaptions. A parsimonious model specification within the linear‐rational class has a very good fit to both interest rate swaps and swaptions since 1997 and captures many features of term structure, volatility, and risk premium dynamics—including when interest rates are close to the zero lower bound.     

ROLE OF VOLUNTARY PROGRAMS IN AGRICULTURAL NONPOINT POLLUTION POLICY

Voluntary programs' effectiveness in reducing agricultural pollution is under debate in the professional literature, within government regulatory agencies, and among legislators. In general, non-farm business owners bear little or none of the costs of environmental degradation that their business activities cause. However, farmers who reside on the farm may bear some of the costs associated with using chemicals. As a result, voluntary programs encouraging adoption of management practices that simultaneously improve on farm and off-farm environmental quality may not require subsidizing farmers for their full loss in profits. However, farmers likely will not adopt regulatory agencies' recommended management practices that do not positively affect on farm environmental quality unless subsidies exceed full adoption costs .
