The Impact of Financial Transaction Taxes on Stock Markets: Short-Run Effects, Long-Run Effects, and Reallocation of Trading Activity
National Tax Journal,
We investigate the French 2012 financial transaction tax (FTT) and find robust evidence for anticipation effects before the implementation date. Controlling for short-run effects, we only find weak evidence for a long-run reduction in trading activity. Thus, the main impact of the French FTT on trading activity is short-run. In line with liquidity clientele effects, we find a more potent effect for low-liquidity stocks and a reallocation of trading to high-liquidity stocks from the Supplemental Liquidity Provider (SLP) program. Finally, we find weak evidence for a persistent volatility reduction but no indication of a significant FTT impact on price efficiency.
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.
Bank Financing, Institutions and Regional Entrepreneurial Activities: Evidence from China
International Review of Economics and Finance,
We investigate the effects of bank financing on regional entrepreneurial activities in China. We present contrasting findings on the role of quantity vs. quality of bank financing on small business formation in China: while we document a consistent, significantly positive relationship between the quality of bank financing and new venture formation, we find that the quantity of supplied credit is insignificant. We report that formal institutions are positively correlated to regional entrepreneurial activities, and informal institutions substitute formal institutions. Our findings also reveal that the institutional environment tends to supplement bank financing in promoting regional entrepreneurial activities.
Business Cylce Effects of the 2014 Oil Price Slump
Wirtschaftskammer Österreich: Wirtschaftspolitische Blätter,
The price for crude oil has dropped remarkably since the middle of the year 2014. Business cycle effects of oil price changes depend on whether these are caused by demand or supply side factors. In the present paper, the decrease in oil prices since the middle of the year 2014 is decomposed into demand side and oil-market specific factors. Subsequently, the contribution of the decline in oil prices to the economic development since the third quarter of 2014 and the expected effects until the end of the year 2016 are analyzed using the international business cycle model of the Halle Institute for Economic Research (IWH). The analysis considers both, oil-exporting countries (Russia) as well as oil-importing economies (G7 countries and Austria). Economic activity is stimulated strongest in the United States and Japan, whereas it is remarkably curbed in Russia.
