This paper investigates the impact of knowledge capital stocks on total factor productivity through the lens of the knowledge capital model proposed by Griliches (1979), augmented with a spatially discounted cross-region knowledge spillover pool variable. The objective is to shift attention from firms and industries to regions and to estimate the impact of cross-region knowledge spillovers on total factor productivity (TFP) in Europe. The dependent variable is the region-level TFP, measured in terms of the superlative TFP index suggested by Caves, Christensen and Diewert (1982). This index describes how efficiently each region transforms physical capital and labour into output. The explanatory variables are internal and out-of-region stocks of knowledge, the latter capturing the contribution of cross-region knowledge spillovers. We construct patent stocks to proxy regional knowledge capital stocks for N=203 regions over the 1997- 2002 time period. In estimating the effects we implement a spatial panel data model that controls for the spatial autocorrelation due to neighbouring regions and the individual heterogeneity across regions. The findings provide a fairly remarkable confirmation of the role of knowledge capital contributing to productivity differences among regions, and add an important spatial dimension to the discussion, by showing that productivity effects of knowledge spillovers increase with geographic proximity.

Based on the gravity model by Baier and Bergstrand (2001), we use a static and dynamic panel data approach to estimate the relative contributions of income growth, income convergence, and the reductions in tariffs and trade costs to the growth of intra-EU trade over the period 1960 to 2000. The results suggest that income growth was the major force, accounting for approximately two third of total growth. Trade liberalization still had a sizeable effect, accounting de facto for the rest of growth, while income convergence played only a minor role. Reductions in trade costs had no significant effect on the growth of intra- EU trade. The results turn out as robust against several robustness checks and the use of alternative estimators. / Series: EI Working Papers / Europainstitut

We estimate the speed of income convergence for a sample of 196 European NUTS 2 regions over the period 1985-1999. So far there is no direct estimator available for dynamic panels with strong spatial dependencies. We propose a two-step procedure, which involves first spatial filtering of the variables to remove the spatial correlation, and application of standard GMM estimators for dynamic panels in a second step. Our results show that ignorance of the spatial correlation leads to potentially misleading results. Applying a system GMM estimator on the filtered variables, we obtain a speed of convergence of 6.9 per cent and a capital elasticity of 0.43. / Series: EI Working Papers / Europainstitut

The paper analyses the relationship between succession and firm performance. Using a unique panel data set on a sample of roughly 4,000 Austrian family firms we examine empirically the impact of past succession as well as future succession plans on employment growth and investment behaviour. Analysing succession plans, we do not find a 'shadow of succession' effect. No significant difference in employment growth and investment behaviour is found between firms that plan to transfer the firm in the next ten years and those who do not. In contrast, past succession exerts a significant and positive employment growth effect which becomes stronger over time. The impact of past succession on investments is also positive but not significantly different from zero. Thus, our findings provide support for the existence of a positive employment shadow after a transfer, whereas the shadow of succession hypothesis has to be rejected prior to transition.

This paper develops an estimator for higher-order spatial autoregressive panel data error component models with spatial autoregressive disturbances, SARAR(R,S). We derive the moment conditions and optimal weighting matrix without distributional assumptions for a generalized moments (GM) estimation procedure of the spatial autoregressive parameters of the disturbance process and define a generalized two-stage least squares estimator for the regression parameters of the model. We prove consistency of the proposed estimators, derive their joint asymptotic distribution, and provide Monte Carlo evidence on their small sample performance.

This paper develops a unified framework for fixed and random effects estimation of higher-order spatial autoregressive panel data models with spatial autoregressive disturbances and heteroskedasticity of unknown form in the idiosyncratic error component. We derive the moment conditions and optimal weighting matrix without distributional assumptions for a generalized moments (GM) estimation procedure of the spatial autoregressive parameters of the disturbance process and define both a random effects and a fixed effects spatial generalized two-stage least squares estimator for the regression parameters of the model. We prove consistency of the proposed estimators and derive their joint asymptotic distribution, which is robust to heteroskedasticity of unknown form in the idiosyncratic error component. Finally, we derive a robust Hausman-test of the spatial random against the spatial fixed effects model. (authors' abstract) / Series: Department of Economics Working Paper Series

A phantom is haunting the EU enlargement process. Some fear that the Balassa-Samuelson (B-S) effect might be a major obstacle for the Central and Eastern European countries (CEEC) to become members of the Economic and Monetary Union (EMU). A review of the relevant literature reveals that most estimations of the B-S effect in the EU acceding countries are flawed by one kind or the other. Either they do not estimate correctly the B-S propositions, or if they measure it they use a variety of measures for the variables needed. Additionally, the B-S effect is only a special case of a broader approach towards equilibrium real exchange rates. Lastly the B-S effect is studied in a CGE multi-country world in order to detect possible spillover effects. After describing the "official" road map towards the EMU, it is concluded that the uncertainties in measuring the B-S are much too high in order to see in it (alone) a major hindrance for the CEEC to become early members of the EMU. Moreover, real exchange rate appreciations that reflect productivity gains in the tradable sector are an equilibrium phenomenon and do not require a policy response. They are a natural phenomena in catching-up countries like the CEEC. Furthermore, the official doctrine for entering the EMU by the EU/ECB only interdicts depreciations but not appreciations for potential EMU members.

This paper examines the impact of financial sector foreign direct investment (FSFDI) on economic growth by estimating a panel data model for 11 Central and Eastern European countries (CEECs) between 1996 and 2003 in a cross-country growth accounting framework. The analysis concentrates on the efficiency channel linking FSFDI to economic growth. The results clearly indicate that there can be a relationship between FSFDI and economic growth. Approaching a medium degree of financial M&A is rewarded by higher economic growth after two periods. Beyond it, FSFDI seems to spur economic growth depending on a higher human capital stock. FSFDI-induced knowledge-spillovers to domestic banks can be an explanation for this phenomenon. Above a certain threshold, the crowding-out of local physical capital caused by the entry of a foreign bank seems to hamper economic growth. The value of the paper lies in (1) providing novel data on FSFDI in CEECs, (2) analyzing the impact of FDI on a sectoral level and (3) in modeling the hitherto only qualitatively discussed relationship between foreign banks and economic development into a structural, econometric model that combines two streams of economic research: the FDI-growth-literature and the finance-growth-literature.

We contribute to the foreign direct investment (FDI) literature by providing first empirical evidence on the relative importance of location fac- tors for service and manufacturing FDI. This is of particular interest as the global stock of inward FDI in the service sector has become predominant in the last ten years. Based on a sectoral panel of eight new European member states in the period of 1998 to 2004 we perform a dynamic panel analysis al- lowing for individual adjustment periods across sectors. Results support our assumption that investment into the service sector, which is characterized by low installation costs, adjusts much faster to its desired level than manufactur- ing FDI. Furthermore, since services are mostly non-tradable, FDI into this sector is largely based on market-seeking motives while manufacturing FDI is also driven by international price competitiveness measured via real unit labor costs.

This paper empirically investigates the key firm- and industry-specific restrictions to the performance of small and medium-sized enterprises (SMEs) in services trade. For this purpose, we use firm-level data from firms in France operating in different services sectors over the time period 1998 to 2007 and formulate two-part models consisting of (i) (dy namic) export equations and (ii) (dynamic) export share equations. Our results confirm the view that a relatively low share of SMEs engage in services trade. In line with the new-new trade theory, our results also corroborate that more productive SMEs have a higher export probability. The key finding of this paper is that the export decisions of SMEs in services sectors are estimated to be extremely persistent, implying that trade pol icy efforts, including the allocation of scarce trade promotion budgets, should be directed at addressing the barriers faced in establishing the first export operation. Finally, our sub-sectoral estimates reveal considerable heterogeneity across different types of services.
