Sequential Procurement With Subcontracting

Two symmetric sellers are approached sequentially by fragmented buyers. Each buyer conducts a second-price auction and purchases from the seller who offers the lower price. Winning an auction affects bidding for future contracts because the sellers have nonconstant marginal costs. We assume that the sellers are completely informed, and we study the unique equilibrium that survives iterated elimination of weakly dominated strategies. If subcontracting between the sellers is impossible, the final allocation of contracts is generally inefficient. If postauction subcontracting is possible, the sellers can be worse off, ex ante , than when subcontracting is impossible.     

Local versus Global Assessment of Mobility*

Mobility indices are popular tools designed to quantify the extent of income changes by aggregating “local” distributional change into a “global” scalar according to some rule. For some mobility measures, this aggregation rule is only implicit in their standard definition. We derive an insightful approximation to the (statistical) aggregation rule for the important class of mobility indices introduced by Shorrocks (Journal of Economic Theory 19 (1978), 376–93) and further generalized by Maasoumi and Zandvakili (Economic Letters 22 (1986), 97–102), which enables us to characterize their normative properties. We also develop methods for estimation and inference. A substantive empirical contribution emerges from the comparison of mobility between the United States and Germany. Our methods reveal why income mobility is higher in Germany than in the United States: Higher German mobility in the bottom of the distribution is combined with an implicitly higher weighting by the mobility index at the bottom.     

The desired level of market orientation and business unit performance

Existing studies of market orientation have hypothesized that the strength of the market orientation/performance relationship depends on environmental variables such as market turbulence, technological turbulence, and competitive intensity. To date most empirical studies have failed to confirm these hypotheses; however, these studies (1) assumed that performance is a linear function of the achieved level of market orientation and (2) tested whether environmental uncertainty moderates this relationship. A complementary explanation for the impact of environmental variables on a firm’s market orientation arises from studies of organizational behavior that link the need for coordination and control to environmental uncertainty and organizational strategy. Building on this perspective, the authors argue that (1) environmental uncertainty influences the desired level of market orientation and (2) the gap between the desired and achieved levels of market orientation influence business unit performance. The authors test these hypotheses with data collected from multiple respondents in 308 US firms. The data analysis confirms that the desired level of market orientation is a function of market turbulence, competitive intensity, technological turbulence, and innovation strategy. In addition, the desired level of market orientation positively influences the achieved level. Finally, when the achieved level of market orientation is less than the desired level, business unit performance is a negative function of the gap between the desired and achieved levels of market orientation.

Minimum wages in Spain

In Spain the minimum wage appears to have no significant employment-reducing effect for workers over 18. For the under 18s, however, minimum wages and employment are negatively related. The government should consider lowering the minimum wage for younger workers.     

Are EU budget deficits stationary?

In this paper, we test for the stationarity of European Union budget deficits over the period 1971–2006, using a panel of thirteen member countries. Our testing strategy addresses two key concerns with regard to unit root panel data testing, namely (1) the presence of cross-sectional dependence among the countries in the panel and (2) the identification of potential structural breaks that might have occurred at different points in time. To address these concerns, we employ an AR-based bootstrap approach that allows us to test the null hypothesis of joint stationarity with endogenously determined structural breaks. In contrast to the existing literature, we find that the EU countries considered are characterised by fiscal stationarity over the full sample period irrespective of us allowing for structural breaks. This conclusion also holds when analysing sub-periods based on before and after the Maastricht treaty.     

Directional heterogeneity of environmental disamenities: the impact of crematory operations on adjacent residential values

A hedonic study of residential house sales in Rawlins, Wyoming, was conducted to estimate the impact of an environmental shock from a new point source upon adjacent residential property values. We use a unique data base of house sale prices and associated house attributes, including structural and neighbourhood characteristics and geographic distances and directions from the source of the shock, atmospheric emissions from a new crematory. Our data spans 27 months of house sales: 7 months before, and 20 months after the startup of crematory operations. Results indicate that proximity, measured both in terms of direction and distance from the crematory, imparts a statistically significant negative impact on average house sale prices–an increase of 0.3 to 3.6% of average sale price for every one-tenth mile increase up to one-half mile in distance away from the crematory, but depending on direction from the crematory. This distance benefit increases somewhat with calendar time only for houses located west of the crematory.
