Does the mere presence of big banks affect macroeconomic outcomes? In this paper, we develop a theory of granularity (Gabaix, 2011) for the banking sector, introducing Bertrand competition and heterogeneous banks charging variable markups. Using this framework, we show conditions under which idiosyncratic shocks to bank lending can generate aggregate fluctuations in the credit supply when the banking ...
Despite high economic growth during the last decades, China is still vulnerable to shocks arising from industrial states. The advanced economies determine Chinese export performance, with subsequent effects on output growth. Using a production function approach, this paper examines to which extent regional GDP growth in China is export driven. In a panel of 28 Chinese provinces, series are splitted ...
This paper investigates the effects of global oil and food price shocks to consumer prices in Middle East-North African (MENA) countries using threshold cointegration methods. Oil and food price shocks increase domestic prices in the long run, whereby the impact of food prices dominates. While global prices are weakly exogenous, consumer prices respond to deviations from the equilibrium relationship. ...
The Chinese growth miracle was based on exports and investment in recent years. While strong output growth has been maintained even during the financial crisis, the imbalances within the country increased. To return to a more sustainable path of development, policies are directed to improve the role of private consumption. However, the institutional framework is an impediment to the transformation, ...
Bank liability guarantee schemes have traditionally been viewed as costless measures to shore up investor confidence and prevent bank runs. However, as the experiences of some European countries, most notably Ireland, have demonstrated, the credibility and effectiveness of these guarantees are crucially intertwined with the sovereign's funding risks. Employing methods from the literature on global ...
We investigate whether people become more willingly self-employed during boom periods or in recessions and to what extent it is the business cycle or the employment status influencing entry rates into entrepreneurship. Our analysis for Germany reveals that start-up activities are positively influenced by unemployment rates and that the cyclical component of real GDP has a negative effect. This implies ...
We explore the impact of large banks and of financial openness for aggregate growth. Large banks matter because of granular effects: if markets are very concentrated in terms of the size distribution of banks, idiosyncratic shocks at the bank-level do not cancel out in the aggregate but can affect macroeconomic outcomes. Financial openness may affect GDP growth in and of itself, and it may also influence ...
We analyse the relationship between the debt to GDP ratio and real per capita GDP growth for the euro area members by distinguishing between periods of sustainable and non-sustainable debt. Thresholds are theory-based and depend on the macroeconomic framework. If the interest rate exceeds nominal output growth, primary budget surpluses are required to achieve a sustainable debt ratio. The negative ...
This paper challenges the common view that exports generally contribute more to GDP growth than a pure change in export volume, as the export-led growth hypothesis predicts. Applying panel cointegration techniques to a production function with non-export GDP as the dependent variable, we find for a sample of 45 developing countries that: (i) exports have a positive short-run effect on non-export GDP ...
