Navigating between dyads and networks

With this article we draw up a panorama of proposed conceptualisations lying between dyad and network. We strive to summarize as far as possible the major dimensions, found in the academic management literature, which have been used to characterise networks. These dimensions are then used to interpret the above conceptualisations. This allows us, to round off, to propose a potential roadmap allowing researchers and practitioners alike the possibility of situating and positioning themselves in the myriad field that could loosely be termed network research.     

Trade reorientation and post-reform productivity growth in Bulgarian enterprises

This paper analyzes the importance of integration into world markets following the collapse of central planning in explaining the productivity growth performance of Bulgarian firms. Using a large panel data set on 1,300 manufacturing firms for 13 quarters, we find that a shift towards sourcing from - and exporting to - OECD markets is a significant factor explaining firm-level total factor productivity growth.     

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.     

Is Mexico a Lumpy Country?

Courant and Deardorff (1992 ) show theoretically that an extremely uneven distribution of factors within a country can induce behavior at odds with overall comparative advantage. We demonstrate the importance of this insight for developing countries. We show that Mexican regions exhibit substantial variation in skill abundance, offer significantly different relative factor rewards, and produce disjoint sets of industries. This heterogeneity helps both to undermine Mexico's aggregate labor abundance and to motivate behavior that is more consistent with relative skill abundance.     

Finding and retaining the dominant strategy: The second-price, English and ‘sealed offer’ English auctions

Using experiments in a procurement setting, this study examined the performance abilities of three auctions: the second-price, English, and a new ‘sealed offer’ English. Additionally, to see if dominant strategy learning would be transferred, after fifteen periods with one of the three auctions, all subjects completed a second 15 periods with the second-price auction. The English auction performed best overall. However, only limited learning was found to occur, with some subjects that had adopted the dominant strategy in the English switching in the second-price. Lessons from the new mechanism transferred better, but initial learning of the dominant strategy was slower.
