Do exporters really pay higher wages? First evidence from German linked employer-employee data
(2006)
Many plant-level studies find that average wages in exporting firms are higher than in non-exporting firms from the same industry and region. This paper uses a large set of linked employer-employee data from Germany to analyze this exporter wage premium. We show that the wage differential becomes smaller but does not completely vanish when observable and unobservable characteristics of the employees and of the work place are controlled for. For example, blue-collar (white-collar) employees working in a plant with an export-sales ratio of 60 percent earn about 1.8 (0.9) percent more than similar employees in otherwise identical non-exporting plants.
This paper discusses the emergence of endogenous redistributive cycles in a stochastic growth model with incomplete asset markets and heterogeneous agents, where agents vote on the degree of progressivity in the taxñtransferñscheme. The model draws from BÈnabou (1996) and ties the bias in the distribution of political power to the degree of inequality in the society, thereby triggering redistributive cycles which then give rise to a nonlinear, cyclical pattern of savings rates, growth and inequality over time.
Using panel data from Spain Farinas and Ruano (IJIO 2005) test three hypotheses from a model by Hopenhayn (Econometrica 1992): (H1) Firms that exit in year t were in t-1 less productive than firms that continue to produce in t. (H2) Firms that enter in year t are less productive than incumbent firms in year t. (H3) Surviving firms from an entry cohort were more productive than non-surviving firms from this cohort in the start year. Results for Spain support all three hypotheses. This paper replicates the study using a unique newly available panel data sets for all manufacturing plants from Germany (1995 – 2002). Again, all three hypotheses are supported empirically.
Ergebnisbericht der Nutzerbefragung in der Bibliothek der Fachhochschule Nordostniedersachsen
(2000)
Im Sommersemester 2000 wurde in der Bibliothek der Fachhochschule Nordostniedersachsen an den Standorten Lüneburg, Suderburg und Buxtehude eine Nutzerbefragung unter 800 Studierenden durchgeführt. Die nach dem Zufallsprinzip ausgewählten Studierenden erhielten einen umfangreichen Fragebogen per Post zugeschickt, den 159 ausfüllten und zurücksandten. Es wurden Fragen zum Nutzungsverhalten und zur Zufriedenheit mit den Dienstleistungen der Bibliothek gestellt. Die Auswertung der Befragung erfolgte mit dem Statistikprogramm SPSS durch den Fachbereich Wirtschaftspsychologie, der auch den vorliegenden Ergebnisbericht erstellte.
Many public goods are characterized by rivalry and/or excludability. This paper introduces both non-excludable and excludable public inputs into a simple endogenous growth model. We derive the equilibrium growth rate and design the optimal tax and user-cost structure. Our results emphasize the role of congestion in determining this optimal financing structure and the consequences this has in turn for the government’s budget. The latter consists of fee and tax revenues that are used to finance the entire public production input and that may or may not suffice to finance the entire public input, depending upon the degree of congestion. We extend the model to allow for monopoly pricing of the user fee by the government. Most of the analysis is conducted for general production functions consistent with endogenous growth, although the case of CES technology is also considered.
Mikroökonometrische Studien mit Firmendaten aus vielen Ländern zeigen, dass exportierende Firmen eine höhere Produktivität aufweisen als Firmen, die lediglich den jeweiligen Binnenmarkt ihres Sitzlandes beliefern, und dass es einen Selbstselektionsprozess der produktiveren Firmen auf Auslandsmärkte gibt, während anderseits Exporttätigkeit nicht unbedingt die Produktivität verbessert. Der vorliegende Beitrag präsentiert empirische Befunde hierzu mit Daten für niedersächsische Industriebetriebe aus den Jahren 1995 bis 2004. Folgende Fragen stehen im Mittelpunkt: Wie unterscheiden sich Produktivität und Produktivitätswachstum zwischen exportierenden und nicht-exportierenden mittelständischen Betrieben? Gehen die produktiveren Betriebe den Schritt auf den Weltmarkt? Führen Exporte zu höherer Produktivität? Die Implikationen der Ergebnisse werden dann vor dem Hintergrund der internationalen Evidenz zum Zusammenhang zwischen Exporttätigkeit und Produktivität diskutiert.
Using unique recently released nationally representative high-quality longitudinal data at the plant level, this paper presents the first comprehensive evidence on the relationship between exports and productivity for Germany, a leading actor on the world market for manufactured goods. It applies and extends the now standard approach from the international literature to document that the positive productivity differential of exporters compared to non-exporters is statistically significant, and substantial, even when observed firm characteristics and unobserved firm specific effects are controlled for. For West German plants (but not for East German plants) some empirical evidence for self-selection of more productive firms into export markets is found. There is no evidence for the hypothesis that plants which start to export perform better in the three years after the start than their counterparts which do not start to sell their products on the world market. Results for West Germany support the hypothesis that the productivity differential between exporters and nonexporters is at least in part the result of a market driven selection process in which those export starters that have low productivity at starting time fail as a successful exporter in the years after the start, and only those that were more productive at starting time continue to export.
While the role of exports in promoting growth in general, and productivity in particular, has been investigated empirically using aggregate data for countries and industries for a long time, only recently have comprehensive longitudinal data at the firm level been used to look at the extent and causes of productivity differentials between exporters and their counterparts which sell on the domestic market only. This papers surveys the empirical strategies applied, and the results produced, in 45 microeconometric studies with data from 33 countries that were published between 1995 and 2004. Details aside, exporters are found to be more productive than non-exporters, and the more productive firms self-select into export markets, while exporting does not necessarily improve productivity.
This paper presents the first empirical test with German establishment level data of a hypothesis derived by Helpman, Melitz and Yeaple in a model that explains the decision of heterogeneous firms to serve foreign markets either trough exports or foreign direct investment: only the more productive firms choose to serve the foreign markets, and the most productive among this group will further choose to serve these markets via foreign direct investments. Using a non-parametric test for first order stochastic dominance it is shown that, in line with this hypothesis, the productivity distribution of foreign direct investors dominates that of exporters, which in turn dominates that of national market suppliers.
