Trade and Productivity in a Transition Economy: the Role of Industry and Export Destination

This paper focuses on the joint role of industry technology intensity and export market characteristics in the analysis of export-related productivity gains. Using a unique database of Ukrainian manufacturing firms in 2000-06, we classify all manufacturing sectors according to their technology intensity and estimate destination-specific learning by exporting effects separately for firms operating in high and low technology sectors. New exporters in high technology sectors enjoy robust long-term productivity growth premia when targeting advanced export markets, consistent with learning through exports. Export entrants in low technology sectors, instead, enjoy mostly short-term productivity improvements regardless of the export destination. Our findings suggest that the systematic distinction between the technology intensity of various industries is a relevant dimension for empirical studies on destination-specific learning by exporting.     

Understanding wage restraint in the German public sector: does the pattern bargaining hypothesis really hold water?

German public sector wage restraint has been explained through the presence of a specific type of inter-sectoral wage coordination in the industrial relations system—that is, export sector-led pattern bargaining. First, as a literature-assessing exercise, this paper reviews the literature in industrial relations and comparative political economy (CPE) and finds that (i) the origins and mechanics of inter-sectoral wage coordination through pattern bargaining have never been laid out clearly; (ii) that the mechanisms of the pattern bargaining thesis have never been tested empirically; and (iii) that the CPE literature reveals an export-sector bias. Second, as a theory-testing exercise, hoop tests are performed to verify the pattern bargaining hypothesis. The key finding is that Germany cannot be considered a case of export sector-driven pattern bargaining, opening a new research agenda for the study of public sector wage setting centred on public sector employment relations, public finance, public administrations and the politics of fiscal policy.

Does Accounting Conservatism Discipline Qualitative Disclosure? Evidence From Tone Management in the MD&A*

We investigate whether accounting conservatism, which has been found to be effective in constraining management opportunism in other settings, constrains upward tone management (UTM) in the Management's Discussion and Analysis (MD&A) portion of the 10-K filing. We hypothesize that conservatism makes it harder for managers to opportunistically downplay bad news and magnify good news when discussing current performance. Consistent with this hypothesis, we find that UTM is negatively associated with several accounting conservatism proxies. Additionally, we hypothesize and find that this association is stronger for firms where managers have higher incentives to manipulate tone. In supplemental analyses, we find evidence to suggest that our results are not due to an endogenous relationship between conservatism and UTM. We also find that conservatism neither encourages downward tone management (DTM) nor constrains managers from conveying real information about future good news. Together, our results suggest that accounting conservatism improves disclosure narratives.     

DEFINING SUPPLY CHAIN MANAGEMENT

A management construct cannot be used effectively by practitioners and researchers if a common agreement on its definition is lacking. Such is the case with the term “supply chain management”—so many definitions are used that there is little consensus on what it means. Thus, the purpose of this paper is to examine the existing research in an effort to understand the concept of “supply chain management.” Various definitions of SCM and “supply chain” are reviewed, categorized, and synthesized. Definitions of supporting constructs of SCM and a framework are then offered to establish a consistent means to conceptualize SCM. Antecedents and consequences of SCM are identified, and the boundaries of SCM in terms of business functions and organizations are proposed. A conceptual model and unified definition of SCM are then presented that indicate the nature, antecedents, and consequences of the phenomena.     

USER INFLUENCE ON THE RELATIONSHIP BETWEEN FORECAST ACCURACY,APPLICATION AND LOGISTICS PERFORMANCE

When companies develop and apply more accurate forecasts in their planning and management activities, they have the potential to improve performance throughout their organization and across the supply chain. To realize these improvements, however, companies must (1) implement techniques and practices that improve forecast accuracy, and (2) integrate the more accurate forecasts into their planning and management activities. While much research has focused on accomplishing the first of these requirements, few studies have investigated the important role that user's play in the application of forecasts for logistics planning and management. This article establishes a connection between forecast performance, user perceptions of the quality of forecasts they receive, the extent that they use the forecasts and the resulting impact on logistics performance.
