Explaining the size differences of exporter premia: theory and evidence

Two decades of research have established pronounced exporter productivity premia (EPP) and exporter size premia (ESP). Yet, we do not know why such exporter premia differ so widely in magnitude across countries or sectors? We take this question to the theory and to the data. We derive the sectoral EPP and ESP in a standard heterogeneous firms trade model and apply the insights from the model to guide our empirical investigation of detailed Danish firm-level data. We show that a significant share of the observed variation in EPP and ESP across sectors can be accounted for by sector differences in the underlying variation in productivity dispersion, variable trade costs, the ratio of fixed export costs to fixed costs of production, and the elasticity of demand.     

The impact of international outsourcing on individual employment security: A micro-level analysis

The paper analyzes how international outsourcing affected individual employment security. The analysis is carried out at the micro-level, combining monthly spell data from household panel data and industry-level outsourcing measures. By utilizing micro-level data, problems such as aggregation and potential endogeneity bias, as well as crude skill approximations that regularly hamper industry level displacement studies, can be reduced considerably. The main finding is that international outsourcing significantly lowers individual employment security. Interestingly, the effect does, however, not differ between high-, medium-, and low-skilled workers but only varies with job duration.     

Winners and losers: a micro-level analysis of international outsourcing and wages

Abstract.  Our paper investigates the link between international outsourcing and wages utilizing a large household panel and combining it with industry-level information on industries' outsourcing activities from input-output tables. This approach avoids problems such as aggregation bias, potential endogeneity bias, and poor skill definitions that commonly hamper industry-level studies. We find that outsourcing has had a marked impact on wages. Applying two alternative skill classifications, we find evidence that a 1 percentage point increase in outsourcing reduced the wage for workers in the lowest skill categories by up to 1.5%, while it increased wages for high-skilled workers by up to 2.6%. This result is robust to a number of different specifications.     

Characterising Euro Area Multinationals

This study uses firm‐level data on a large sample of European manufacturing firms to investigate the links between opening up foreign affiliates and firms’ productivity. The analysis is guided by recent theoretical models of international trade with firm heterogeneity. The paper finds that while only a small share of euro area firms locate affiliates abroad, these firms account for over‐proportionally large shares of output, employment and profits in their home countries. They have higher survival rates and their productivity growth is also higher. The strongest contribution is by productivity growth of existing firms with a multinational status rather than entry into the multinational status. Finally, there are performance premia for multinationals with a large number of affiliates abroad relative to those with a small number.     

One‐off export events

Isolated single‐month, one‐off export transactions (observed once in a 49‐month window) turn out to be the dominant spell length in granular firm–product–destination trade data. Moreover, on average, for an export‐active firm, such one‐off events generate a significant part of foreign sales. These patterns cannot be explained by the lumpiness of trade (e.g., seasonal shipments), nor do they sit well with available trade models. To reconcile theory with the data, we introduce passive (i.e., unsolicited buyer‐side driven) exporting in addition to proactive exporting. Our empirical investigation establishes novel stylized facts on firm and destination characteristics associated with one‐off exporting.     

Offshoring and job loss fears: An econometric analysis of individual perceptions

We quantify the impact of offshoring and other globalisation measures on individual perceptions of job security. For the analysis we combine industry-level offshoring measures with micro-level data from a large German household panel survey and estimate ordinal fixed effects models. Our results indicate that offshoring to low-wage countries significantly raises job loss fears whilst offshoring to high-wage countries somewhat lowers them. Over our sample period from 1995 to 2006, offshoring to low and high-wage countries together can account for about 13% of the total increase in job loss fears. High-skilled workers are more sensitive to offshoring although their objective job loss risk is lower relative to low-skilled workers, which we argue reflects the fact that they have more to lose from unemployment.     

Landing on all fours? Communist elites in post-Soviet Russia

This paper analyzes the economic situation of former Communist party members in post-Soviet Russia. On the basis of the Russian Socio-Economic Transition Panel, we are able to identify members of the Communist party prior to transition so that we can assess their relative economic performance between 1993 and 1999. We find a significant wage premium associated with former membership in the Soviet Communist party during the period from 1993 to 1999. After addressing non-random selection into the Communist party using an instrumental variables approach, we demonstrate that the overall Communist wage premium can be attributed to positive unobservable characteristics of former party members.

Is there a wage premium for volunteer OSS engagement? – signalling,learning and noise

Volunteer-based open-source production has become a significant new model for the organization of software development. Economics often pictures this phenomenon as a case of signalling: individuals engage in the volunteer programming of open-source software (OSS) as a labour-market signal resulting in a wage premium. Yet, this explanation could so far not be empirically tested. This article fills this gap by estimating an upper-bound composite wage premium of voluntary OSS contributions and by separating the potential signalling effect of OSS engagement from other effects. Although some 70% of OSS contributors believe that OSS involvement benefits their careers, we find no actual labour-market premium for OSS engagement. The presence of other motives, such as fun of play or altruism, renders OSS contributions too noisy to function as a signal.     

Does Outsourcing to Central and Eastern Europe Really Threaten Manual Workers’ Jobs in Germany?

Starting from the observation of significant within‐industry skill‐upgrading, this paper analyses how international outsourcing has affected the relative demand for manual workers in German manufacturing during the 1990s. We combine trade and input‐output data to disentangle international outsourcing and trade in final goods and differentiate between the effects of narrowly and broadly defined outsourcing towards Central and Eastern Europe (CEEC), the European Union (EU15) and the rest of the world. Accounting for the endogeneity of international outsourcing by applying instrumental variable techniques, the empirical analysis showed that international outsourcing is indeed an important explanatory factor for the observed decline in relative demand for manual workers in German manufacturing. Particularly, outsourcing towards CEEC plays a major role, irrespective of whether a narrow or wide measure of outsourcing is applied. Using a narrow outsourcing measure and controlling for the adverse demand effects of skill‐biased technological change, time‐changing industry characteristics, wages as well as industry unobserved characteristics, international outsourcing towards CEEC is found to have lowered the manual workers’ wage bill share by 2.7 per‐centage points between 1991 and 2000. In its magnitude this effect is comparable to the skill‐biased effect of technological progress, as captured by our controls. Outsourcing towards countries outside CEEC and outside the EU15 is found to have small negative effects on the relative demand for manual workers, but only if one follows the broad definition of international outsourcing. Outsourcing towards the EU15 is, however, always found to be insignificant.     

Do labour market institutions matter? Micro-level wage effects of international outsourcing in three European countries

This paper studies the impact of outsourcing on individual wages in three European countries with markedly different labour market institutions: Germany, the UK and Denmark. To do so we use individual-level data sets for the three countries and construct comparable measures of outsourcing at the industry level, distinguishing outsourcing by broad region. We discuss some possible intuitive reasons for why there may be differences in the impact of outsourcing across the three countries, based on labour market institutions.
