Contestability, Technology and Banking

Abstract
We estimate the effect of internet penetration on retail bank margins in the euro area. Based on an adapted Baumol [1982] type contestability model, we argue that the internet has reduced sunk costs and therefore increased contestability in retail banking. We test this conjecture by estimating the model using semi-aggregated data for a panel of euro area countries. We utilise time series and cross-sectional variation in internet penetration. We find support for an increase in contestability in deposit markets, and no effect for loan markets. The paper suggests that for time and savings deposits, the presence of brick and mortar bank branches may no longer be of first order importance for the assessment of the competitive structure of the market.

FDI and Domestic Investment: An Industry-level View
Claudia M. Buch
CEPR. Discussion Paper No. 6464,
2007
Abstract
Previous empirical work on the link between domestic and foreign investment provides mixed results which partly depend on the level of aggregation of the data. We argue that the aggregated home country implications of foreign direct investment (FDI) cannot be gauged using firm-level data. Aggregated data, in turn, miss channels through which domestic and foreign activities interact. Instead, industry-level data provide useful information on the link between domestic and foreign investment. We theoretically show that the effects of FDI on the domestic capital stock depend on the structure of industries and the relative importance of domestic and multinational firms. Our model allows distinguishing intra-sector competition from inter-sector linkage effects. We test the model using data on German FDI. Using panel cointegration methods, we find evidence for a positive long-run impact of FDI on the domestic capital stock and on the stock of inward FDI. Effects of FDI on the domestic capital stock are driven mainly by intra-sector effects. For inward FDI, inter-sector linkages matter as well.

Inflation and relative price variability in the euro area: evidence from a panel threshold model
Dieter Nautz, Juliane Scharff
Bundesbank Discussion Paper, No. 14/2006,
2006
Abstract
In recent macroeconomic theory, relative price variability (RPV) generates the
central distortions of inflation. This paper provides first evidence on the empirical
relation between inflation and RPV in the euro area focusing on threshold effects
of inflation. We find that expected inflation significantly increases RPV if inflation
is either very low (below -1.38% p.a.) or very high (above 5.94% p.a.). In the
intermediate regime, however, expected inflation has no distorting effects which
supports price stability as an outcome of optimal monetary policy.

The relationship between unemployment and output in post-communist countries
Hubert Gabrisch, Herbert Buscher
Post-Communist Economies,
2006
Abstract
Unemployment is still disappointingly high in most Central and East European countries, and might be a reflection of the ongoing adjustment to institutional shocks resulting from systemic transition, or it may be caused by high labour market rigidity, or aggregate demand that is too weak. In this paper we have investigated the dynamics of unemployment and output in those eight post-communist countries, which entered the EU in 2004. We used a model related to Okun’s Law; i.e. the first differences in unemployment rates were regressed on GDP growth rates. We estimated country and panel regressions with instrument variables (TSLS) and applied a few tests to the data and regression results. We assume transition of labour markets to be accomplished when a robust relationship exists between unemployment rate changes and GDP growth. Moreover, the estimated coefficients contain information about labour market rigidity and unemployment thresholds of output growth. Our results suggest that the transition of labour markets can be regarded as completed since unemployment responds to output changes and not to a changing institutional environment that destroys jobs in the state sector. The regression coefficients have demonstrated that a high trend rate of productivity and a high unemployment intensity of output growth have been occurring since 1998. Therefore, we conclude that labour market rigidities do not play an important role in explaining high unemployment rates. However, GDP growth is dominated by productivity progress and the employment-relevant component of aggregate demand is too low to reduce the high level of unemployment substantially.

Who Invests in Training if Contracts are Temporary? - Empirical Evidence for Germany Using Selection Correction
Jan Sauermann
IWH Discussion Papers,
Nr. 14,
2006
Abstract
This study deals with the effect of fixed-term contracts on work-related training. Though previous studies found a negative effect of fixed-term contracts on the participation in training, from the theoretical point of view it is not clear whether workers with fixed-term contracts receive less or more training, compared to workers with permanent contracts. In addition to the existing strand of literature, we especially distinguish between employer- and employee-financed training in order to allow for diverging investment patterns of worker and firm. Using data from the German Socio-Economic Panel (GSOEP), we estimate a bivariate probit model to control for selection effects that may arise from unobservable factors, affecting both participation in training and holding fixed-term contracts. Finding negative effects for employer-sponsored, as well as for employee-sponsored training, leads us to conclude that workers with fixed-term contracts do not compensate for lower firm investments.

Forced to Freedom? Empirical Relations between Aid and Economic Freedom
Tobias Knedlik, Franz Kronthaler
IWH Discussion Papers,
Nr. 8,
2006
Abstract
The paper explores the relationships between economic freedom on the one side and development aid and IMF credit as approximation for conditional aid on the other side. After a short review of current literature on the issue of economic development, economic freedom, aid, and IMF credit, the paper develops a simple panel regression model to evaluate the relationship between “economic freedom” as dependent variable and “aid” and “IMF credit” as independent variables. The estimation is based upon data taken from the World Bank’s World Development Indicators and the Heritage Index of Economic Freedom. In contrast to previous research, our results allow the rejection of the hypothesis that IMF credit increases economic freedom and that aid is not contributing to economic freedom. The estimation results suggest that, firstly, aid is positively correlated with economic freedom, and secondly, that IMF credit is negatively correlated with economic freedom. Taking IMF credit as proxy for conditional aid, we conclude that for the period of observation it could not be shown that countries can be forced to economic freedom by aid conditions.
