Abstract
Using a novel proxy of investors' speculative demand constructed from online search interest in investment concepts, we examine how speculative demand affects the returns of Chinese stocks. We find that speculative demand increases following high market returns and predicts subsequent return reversals. Moreover, the speculative demand explains more variation in subsequent returns of A shares (more populated by retail investors) than B shares (less populated by retail investors). Our findings support the recently developed attention theory.

Time-varying Volatility, Financial Intermediation and Monetary Policy
S. Eickmeier, N. Metiu, Esteban Prieto
IWH Discussion Papers,
Nr. 19,
2016
Abstract
We document that expansionary monetary policy shocks are less effective at stimulating output and investment in periods of high volatility compared to periods of low volatility, using a regime-switching vector autoregression. Exogenous policy changes are identified by adapting an external instruments approach to the non-linear model. The lower effectiveness of monetary policy can be linked to weaker responses of credit costs, suggesting a financial accelerator mechanism that is weaker in high volatility periods. To rationalize our robust empirical results, we use a macroeconomic model in which financial intermediaries endogenously choose their capital structure. In the model, the leverage choice of banks depends on the volatility of aggregate shocks. In low volatility periods, financial intermediaries lever up, which makes their balance sheets more sensitive to aggregate shocks and the financial accelerator more effective. On the contrary, in high volatility periods, banks decrease leverage, which renders the financial accelerator less effective; this in turn decreases the ability of monetary policy to improve funding conditions and credit supply, and thereby to stimulate the economy. Hence, we provide a novel explanation for the non-linear effects of monetary stimuli observed in the data, linking the effectiveness of monetary policy to the procyclicality of leverage.

Identifying the Effects of Place-based Policies – Causal Evidence from Germany
Matthias Brachert, Eva Dettmann, Mirko Titze
IWH Discussion Papers,
Nr. 18,
2016
Abstract
The German government provides discretionary investment grants to structurally weak regions to reduce regional disparities. We use a regression discontinuity design that exploits an exogenous discrete jump in the probability of receiving investment grants to identify the causal effects of the investment grant on regional outcomes. We find positive effects for regional gross value-added and productivity growth, but no effects for employment and gross wage growth.

The Political Determinants of Government Bond Holdings
Stefan Eichler, Timo Plaga
Abstract
This paper analyzes the link between political factors and sovereign bond holdings of US investors in 60 countries over the 2003-2013 period. We find that, in general, US investors hold more bonds in countries with few political constraints on the government. Moreover, US investors respond to increased uncertainty around major elections by reducing government bond holdings. These effects are particularly significant in democratic regimes and countries with sound institutions, which enable effective implementation of fiscal consolidation measures or economic reforms. In countries characterized by high current default risk or a sovereign default history, US investors show a tendency towards favoring higher political constraints as this makes sovereign default more difficult for the government. Political instability, characterized by the fluctuation in political veto players, reduces US investment in government bonds. This effect is more pronounced in countries with low sovereign solvency.

Asymmetric Investment Responses to Firm-specific Uncertainty
Julian Berner, Manuel Buchholz, Lena Tonzer
Abstract
This paper analyzes how firm-specific uncertainty affects firms’ propensity to invest. We measure firm-specific uncertainty as firms’ absolute forecast errors derived from survey data of German manufacturing firms over 2007–2011. In line with the literature, our empirical findings reveal a negative impact of firm-specific uncertainty on investment. However, further results show that the investment response is asymmetric, depending on the size and direction of the forecast error. The investment propensity declines significantly if the realized situation is worse than expected. However, firms do not adjust their investment if the realized situation is better than expected, which suggests that the uncertainty effect counteracts the positive effect due to unexpectedly favorable business conditions. This can be one explanation behind the phenomenon of slow recovery in the aftermath of financial crises. Additional results show that the forecast error is highly concurrent with an ex-ante measure of firm-specific uncertainty we obtain from the survey data. Furthermore, the effect of firm-specific uncertainty is enforced for firms that face a tighter financing situation.

To Separate or not to Separate Investment from Commercial Banking? An Empirical Analysis of Attention Distortion under Multiple Tasks
Reint E. Gropp, K. Park
IWH Discussion Papers,
Nr. 2,
2016
Abstract
In the wake of the 2008/2009 financial crisis, a number of policy reports (Vickers, Liikanen, Volcker) proposed to separate investment banking from commercial banking to increase financial stability. This paper empirically examines one theoretical justification for these proposals, namely attention distortion under multiple tasks as in Holmstrom and Milgrom (1991). Universal banks can be viewed as combining two different tasks (investment banking and commercial banking) in the same organization. We estimate pay-performance sensitivities for different segments within universal banks and for pure investment and commercial banks. We show that the pay-performance sensitivity is higher in investment banking than in commercial banking, no matter whether it is organized as part of a universal bank or in a separate institution. Next, the paper shows that relative pay-performance sensitivities of investment and commercial banking are negatively related to the quality of the loan portfolio in universal banks. Depending on the specification, we obtain a reduction in problem loans when investment banking is removed from commercial banks of up to 12 percent. We interpret the evidence to imply that the higher pay-performance sensitivity in investment banking directs the attention of managers away from commercial banking within universal banks, consistent with Holmstrom and Milgrom (1991). Separation of investment banking and commercial banking may indeed be associated with a reduction in risk in commercial banking.

Determinants of the Size of the Sovereign Credit Default Swap Market
Tobias Berg, Daniel Streitz
Journal of Fixed Income,
Nr. 3,
2016
Abstract
We analyze the sovereign credit default swap (CDS) market for 57 countries, using a novel dataset comprising weekly positions and turnover data. We document that CDS markets—measured relative to a country’s debt—are larger for smaller countries, countries with a rating just above the investment-grade cutoff, and countries with weaker creditor rights. Analyzing changes in credit risk, we find that rating changes matter but only for negative rating events (downgrades and negative outlooks). In particular, weeks with downgrades and negative outlooks are associated with a significantly higher turnover in the sovereign CDS market, even after controlling for changes in sovereign CDS spreads. We conclude that agencies’ ratings are a major determinant of the size of the sovereign CDS market.

The Effect of Personal Bankruptcy Exemptions on Investment in Home Equity
S. Corradin, Reint E. Gropp, H. Huizinga, Luc Laeven
Journal of Financial Intermediation,
January
2016
Abstract
Homestead exemptions to personal bankruptcy allow households to retain their home equity up to a limit determined at the state level. Households that may experience bankruptcy thus have an incentive to bias their portfolios towards home equity. Using US household data for the period 1996 to 2006, we find that household demand for real estate is relatively high if the marginal investment in home equity is covered by the exemption. The home equity bias is more pronounced for younger and less healthy households that face more financial uncertainty and therefore have a higher ex ante probability of bankruptcy. These results suggest that homestead exemptions have an important bearing on the portfolio allocation of US households and the extent to which they insure against bad shocks.

Foreign Direct Investment: The Role of Institutional and Cultural Determinants
Stefan Eichler, N. Lucke
Applied Economics,
Nr. 11,
2016
Abstract
Using panel data for 29 source and 65 host countries in the period 1995–2009, we examine the determinants of bilateral FDI stocks, focusing on institutional and cultural factors. The results reveal that institutional and cultural distance is important and that FDI has a predominantly regional aspect. FDI to developing countries is positively affected by better institutions in the host country, while foreign investors prefer to invest in developed countries that are more corrupt and politically unstable compared to home. The results indicate that foreign investors prefer to invest in countries with less diverse societies than their own.
