Short‐term Consequences of Trade Reform for Industry Employment and Wages: Survey of Evidence from Colombia

Recent research has focused on the short‐ to medium‐term implications of trade reforms for the labour market outcomes and poverty in poor economies. This article summarises the evidence on the short‐term consequences of the Colombian trade reform initiated in 1985 for industry employment and industry wages. Although the reform reduced manufacturing tariffs on average by 40 percentage points from 1984 to 1994, tariff declines were not significantly associated with labour reallocation across sectors. The reform, however, was associated with bigger declines in relative industry wages in sectors that experienced bigger tariff cuts. This evidence is in line with the predictions of short‐ to medium‐run models of trade in which labour is not mobile across sectors. It is also consistent with the predictions of models where imperfectly competitive industries share rents with workers and trade reduces the firms’ profit margins and thus workers’ rents.     

Mixing process-generated data in market sociology

Mixed methods researchers often neglect the methodological discussion on data in general and process-generated data specifically. Assuming that the advantages and disadvantages of surveys, interviews and observations are well-known, the author discusses when and why researchers should prefer process-generated data to research-elicited data in market sociology. The author then compares four different types of process-generated data (aggregated statistical data, business directories, newspaper articles, engineering literature). For each data type, the author (a) describes the data type, (b) illustrates what kind of information researchers can gain from this data type and (c) discusses the draw-backs and limits of the data. The article concludes with a discussion of what one can learn for mixing methods and market sociology from this example and why primary data might be useful as an alternative data source after all.     

The Contribution of Small and Medium Enterprises to Economic Development in Ukraine and Belarus: Some Policy Perspectives

The paper considers the development of small and medium enterprises (SME) in two transition economies where market reforms have been slow (Ukraine and Belarus), focusing specifically on the role of government in the process. Empirical data from a study on SMEs and economic development in Ukraine, Belarus and Moldova are used to consider the contribution of SMEs to different aspects of transformation whilst data from a second project are used to show the support needs of SMEs.Following the introduction, which summarises the aims and methodology, the second section presents brief profiles of the context for SME development in each country. Part 3 summarises some of the main empirical findings, focusing on those aspects that have potential policy significance, specifically with respect to employment, innovation, and market orientation, whilst the fourth section considers survey evidence of the support needs of SMEs. The final section draws out the main policy implications of the findings, whilst also setting out an agenda designed to increase the contribution of SMEs to economic development in the future.On the whole, the empirical results demonstrate that some SMEs have developed in Belarus and Ukraine despite the actions of governments, although the number of private enterprises per capita remains small and their qualitative characteristics often reflect the difficult operating conditions. As a result, their contribution to economic and social change is less than it could be, mainly due to an unstable environment and an institutional context that has yet to establish the framework conditions for sustainable private sector development. In terms of policy priorities, the survey data suggest that reform of the distorted legal and financial infrastructures that exist in these countries is the highest priority need.     

Liquidity Constraints and Investment in Transition Economies

We use Bulgarian firm-level data to investigate the impact of liquidity constraints on investment performance. Internal funds are an important determinant of investment in most industrialized countries. We test whether internal funds are important for firm investment during the current transition process in Bulgaria. We use a simple accelerator model of investment to test whether liquidity constraints are relevant in the case of Bulgaria. Our estimations are based on data for the period 1993–95, prior to the Bulgarian financial crisis in 1996–97. It turns out that Bulgarian firms are liquidity constrained, and that firms' size and financial structure help to distinguish between firms that are more and less liquidity constrained. In our view, liquidity constraints can be given a different interpretation in the case of transition economies as compared to Western economies. A more in depth analysis of the data reveals that liquidity constraints, and consequently the access to external funds for Bulgarian firm investment, are to be seen against the background of soft-budget constraints and the failure of the financial system to enforce an efficient allocation of funds. In our view, the lack of liquidity constraints may actually be seen as a sign of financial weakness in the case of Bulgaria.     

The Effect of Marriage on Education of Immigrants: Evidence from a Policy Reform Restricting Marriage Migration*

We investigate the effect of immigrants’ marriage behavior on dropout from education. To identify the causal effect, we exploit a recent Danish policy reform that generated exogenous variation in marriage behavior by a complete abolishment of marriage migration for immigrants below 24 years. The reform influenced immigrants from countries with a high historical rate of marriage migration more than immigrants from country groups with a low rate. We find that the dropout rate for males increases by 25 percentage points as a consequence of marriage to a marriage migrant, whereas the effect for females is small and mostly insignificant.

Let the evidence speak again! Financial incentives are more effective than we thought

In this essay, the authors rejoin the debate about financial incentive effectiveness. They (a) briefly review the state of the literature in 1998, (b) highlight new meta‐analytic findings and update conclusions regarding the financial incentives–performance relationship, (c) address the myth that financial incentives erode intrinsic motivation, (d) provide explanations for the presumed failure of financial incentives and (e) offer some concluding thoughts and suggestions for future research.     

WTO争端解决机制下药品专利保护案对我国的启示

美诉印度药品和农业化学产品专利保护等案涉及的问题：未公布的行政做法与透明度原则的关系、DSH推理中司法经济原则之运用、不同成员基于同一事由再次申诉、专家组报告作为先例的约束力等，这些对我国有一定启示。结合我国目前药品专利实施情况，应运用公共利益原则，适当延长药品专利保护期；专利保护期将尽时对仿制药品予以保护。
