The Impact of Overconfident Customers on Supplier Firm Risks
Journal of Economic Behavior and Organization,
Research has shown that firms with overconfident chief executive officers (CEOs) tend to overinvest and are exposed to high risks due to unrealistically optimistic estimates of their firms’ future performance. This study finds evidence that overconfident CEOs also affect suppliers’ risk taking. Specifically, serving overconfident customers can lead to high supplier risks, measured by stock volatility, idiosyncratic risk, and market risk. The effects are pronounced when customers aggressively invest in research and development (R&D). Our results are robust after addressing self-selection bias and using different CEO overconfidence measures. We also document some real effects of customer CEO overconfidence on suppliers.
30 Years after Reunification, Gross Domestic Product has Served its Purpose as an Indicator
Konferenzband "30 Jahre Deutsche Einheit", März
The comparison of living conditions in East and West Germany is often based on the gross domestic product per inhabitant. However, this measure is not a good welfare indicator in itself. It can be assumed that, measured by the gross domestic product per inhabitant, there will be no further significant equalisation of economic power in East and West Germany in the foreseeable future. This is because the age structure of East Germany, i.e. the ratio of employed persons to inhabitants, is less favourable than in the West. On the other hand, if one looks at important welfare indicators such as consumption opportunities, life expectancy, leisure time and income inequality, living conditions in East and West Germany are more similar than the gross domestic product per inhabitant suggests. In the debates on the catching-up process of East Germany, more emphasis should therefore be placed on labour productivity as a measure of economic strength and on welfare indicators as a measure of the equalisation of living conditions.
