What is beneath the surface? Option pricing with multifrequency latent states
We introduce a tractable class of non-ane price processes with multifrequency stochastic volatil- ity and jumps. The specications require few xed parameters and deliver fast option pricing. One key ingredient is a tight link between jumps and volatility regimes, as asset pricing theory suggests. Empirically, the model matches implied volatility surfaces and their dynamics with- out...

COMFORT: A common market factor non-Gaussian returns model
A new multivariate time series model with various attractive properties is motivated and studied. By extending the CCC model in several ways, it allows for all the primary stylized facts of financial asset returns, including volatility clustering, non-normality (excess kurtosis and asymmetry), and also dynamics in the dependency between assets over time. A fast EM-algorithm is...

Monetary policy, risk-taking and pricing: Evidence from a quasi-natural experiment
We study the risk-taking channel of monetary policy in Bolivia, a dollarized country where monetary changes are transmitted exogenously from the USA. We find that a lower policy rate spurs the granting of riskier loans, to borrowers with worse credit histories, lower ex-ante internal ratings, and weaker ex-post performance (acutely so when the rate subsequently increases). Effects...

Willingness to be financially informed and the benefits of nudging investors to do so
Bhattacharya et al. (2012) shows that many investors are reluctant to accept and follow financial advice. This study analyzes three possibilities which could cause this misbehavior: non-monetary costs, willingness to become informed and comprehensibility of financial information. As so many investors do not accept financial advice, the study further analyzes if it is beneficial to...

Monetary conditions and banks' behaviour in the Czech Republic
This paper examines the impact of monetary conditions on the risk-taking behaviour of banks in the Czech Republic by analysing the comprehensive credit register of the Czech National Bank. Our duration analysis indicates that expansionary monetary conditions promote risk-taking among banks. At the same time, a lower interest rate during the life of a loan reduces its riskiness. While...

Risk preferences are not time preferences: balancing on a budget line: comment
In a recent experimental study of intertemporal risky decision making, Andreoni and Sprenger (2012) find that subjects exhibit a preference for intertemporal diversification, which is inconsistent with discounted expected utility theory. It was claimed that their results are also at odds with models involving probability weighting, such as rank-dependent utility and cumulative...

Diversification, protection of liability holders and regulatory arbitrage
Any solvency regime for financial institutions should be aligned with the two fundamental objectives of regulation: protecting liability holders and securing the stability of the financial system. From these objectives wederive two normative requirements for capital adequacy tests, called surplus and numeraire invariance, respectively. We characterize capital adequacy tests that...

Agency problems, recapitalization costs and optimal resolution of financial distress
We introduce in a dynamic–contracting framework with moral hazard the possibility of recapitalization as an alternative to liquidation when a firm is in financial distress. This is achieved by considering a loss–averse agent and by allowing (but not requiring) the latter to inject additional capital into the firm when necessary. We show that firm recapitalization may arise in an...

Framing effects and risk perception: testing graphical representations of risk for the KIID
In this paper we analyze which graphical representation of risk is most effective in supporting investors to assess the risk and return characteristics of a fund. Moreover, we test on which criteria the investors base their risk taking behavior. To this end we compare return bar charts and price line charts, combined with some additional information such as a risk scale or a gain and...

Dynamics of innovation and risks
We study the dynamics of an innovative industry when agents learn about its strength, i.e., the likelihood that it gets hit by negative shocks. Managers can exert risk-prevention effort to mitigate the consequences of such shocks. As time goes by, if no shock occurs, confidence improves. This attracts managers to the innovative sector. But, when confidence becomes high, less managers...

Risk and Return around the Clock
We investigate price discovery over the 24-hour trading day for equities, currencies, bonds, and commodities. Sizable price discovery occurs around the clock for most assets. For a given asset, intraday risk and return distributions are fairly similar, indicating a broadly constant risk-return-relationship during the day. Although the amount of price discovery varies significantly...

Is there room for geoengineering in the optimal climate policy mix?
We investigate geoengineering as a possible substitute for adaptation and mitigation measures to address climate change. With the help of an integrated assessment model, we distinguish between the effects of solar radiation management on atmospheric temperature levels and its side-effects on ecosystems. To address the uncertainty regarding the magnitude of side-effects, we rely on a...

Measuring and aggregating social performance of microfinance investment vehicles
This paper develops a method to measure and compare social performance of microfinance investments at the level of microfinance investment vehicles. Drawing from measurement theory, it develops formal quality criteria that individual social performance indicators, the selection, and the aggregation of such indicators into a single metric need to satisfy. Social performance indicators...

Economic Momentum and Currency Returns
Past trends in a broad range of fundamental variables predict currency returns. We document that a trading strategy that goes long currencies in countries with strong economic momentum and short currencies in countries with weak economic momen- tum exhibits an annualized Sharpe ratio of about one and yields a significant alpha when controlling for standard carry, momentum, and value...

Central Bank Collateral Frameworks
This paper seeks to inform about a feature of monetary policy that is largely overlooked, yet occupies a central role in modern monetary and financial systems, namely central bank collateral frameworks. Their importance can be understood by the observation that the money at the core of these systems, central bank money, is injected into the economy on terms, not defined in a market,...

Taking Banks to Solow
We develop a simple integration of banks into the Solow model. The objective is to provide a tractable benchmark for analyzing the long-term impact of crises on economic activities and growth. A fraction of firms have to rely on banks for financing their investments while banks face themselves an endogenous leverage constraint. Informed lending by banks and uninformed lending through...

Quantification and characteristics of household inflation expectations in Switzerland
Inflation expectations are a key variable in conducting monetary policy. However, these expectations are generally unobservable and only certain proxy variables exist, such as surveys on inflation expectations. This article offers guidance on the appropriate quantification of household inflation expectations in the Swiss Consumer Survey, where answers are qualitative in nature. We...

Collateral requirements and asset prices
Many assets derive their value not only from future cash flows but also from their ability to serve as collateral. In this paper, we investigate this collateral premium and its impact on asset returns in an infinite-horizon general equilibrium model with heterogeneous agents facing col- lateral constraints for borrowing. We document that borrowing against collateral substantially...

The shadow cost of repos and bank liability structure
Making use of a structural model that allows for optimal liquidity management, we study the role that repos play in a bank's financing structure. In our model the bank's assets consist of illiquid loans and liquid reserves and are financed by a combination of repos, long--term debt, deposits and equity. Repos are a cheap source of funding, but they are subject to an...
