Factors influencing quality of experience of commonly used mobile applications
Increasingly, we use mobile applications and services in our daily life activities, to support our needs for information, communication or leisure. However, user acceptance of a mobile application depends on at least two conditions; the application's perceived experience and the appropriateness of the application to the user's context and needs. Yet, we have a weak...

The effect of proactive adaptation on green investment
Climate change is one of the greatest challenges facing our planet in the foreseeable future anddespite the urgency of the situation global GHG emissions are still increasing. In this context,and since future climate changes appear now unavoidable to some extent, adaptation measureshave recently gained a new political momentum as an important component of climate policies.Contrary to...

Measuring economic uncertainty and its impact on the stock market
This paper proposes a novel measure of economic uncertainty based on the frequency of internet searches. The theoretical motivation is offered by findings in economic psychology that agents respond to increased uncertainty by intensifying their information search. The main advantages of using internet searches are broad reach, timeliness and the fact that they reflect actions, rather...

International price and earnings momentum
We find that price and earnings momentum are pervasive features of international equity markets even when controlling for data snooping biases. For European countries, we find that price momentum is subsumed by earnings momentum on an aggregate level. However, this rationale does not apply to each and every country. While the above explanation is confined to certain time periods in...

Options on realized variance in Log-OU models
We study the pricing of options on realized variance in a general class of Log-OU stochastic volatility models. The class includes several important models proposed in the literature. Having as common feature the log-normal law of instantaneous variance, the application of standard Fourier-Laplace transform methods is not feasible. We derive extensions of Asian pricing methods, to...

A remark on Lin's and Chang's pager 'Consistent modelling of S&P500 and VIX derivatives'
Lin and Chang (2009, 2010) establish a VIX futures and option pricing theory when modelingS&P 500 index by using a stochastic volatility process with asset return and volatility jumps.In this note, we prove that Lin and Chang's formula is not an exact solution of their pricingequation. More generally, we show that the characteristic function of their pricing equationcannot...

Options on realized variance by transform methods: A non-affine stochastic volatility model
In this paper we study the pricing and hedging of options on realized variance in the 3/2 non-affine stochastic volatility model by developing efficient transform-based pricing methods. This non-affine model gives prices of options on realized variance that allow upward-sloping implied volatility of variance smiles. Heston's model [Rev. Financial Stud., 1993, 6, 327–343], the...

Data snooping and the global accrual anomaly
Naively testing for accruals mispricing in 26 equity markets - one market at a time - we find statistical evidence of anomalous returns in some countries. However, some of these findings might well be spurious because of data snooping biases that arise when simultaneously testing several hypotheses. While the accrual anomaly is not deemed to be robust in some countries when properly...

Swiss Banking Secrecy: The Stock Market Evidence
We examine the stock price reactions of four Swiss banks to negotiations between Switzerland and the European Union and between Switzerland and the United States to (i) obtain an estimate of the value of banking secrecy to Swiss banks, and (ii) distinguish between tax evasion and genuine privacy concerns as sources of that value. We find that the value of banking secrecy to the...

Agency Issues and Financing Constraints - Evidence from REITs
Given a firms investment policy, its dividend policy is irrelevant (Miller and Modigliani (1961)). REITs, by law, pay at least 90 % of their corporate income as dividends, so that their dividend policy is given. This is a reversal of the dividend irrelevance theorem through regulatory means. Such a high dividend payment also means lower retained earnings, leaving firms with little...

Dynamic competitive economies with complete markets and collateral constraints
In this paper we examine the competitive equilibria of a dynamic stochastic economywith complete markets. We show that the completeness of the market requires both theset of asset payo¤s and collateral levels to be su¢ ciently rich, so as to allow to decentral-ize the equilibrium allocations obtained in Arrow-Debreu markets subject to a series ofappropriate limited pledgeability...

Peer effects at work: The common stock investments of co-workers
Stock market behavior of individual investors is highly correlated with stock market behavior of their co-workers. For example, a ten percentage point increase in the fraction of co-workers that purchase stocks in a given month is associated with a two percentage point increase in the likelihood of individuals making a purchase. The high correlation exists even after taking...

Evidence of excess comovement in US mergers
This paper considers changes in market comovement of merging US firms. Comparing the expected to the actual post merger comovement, we find that the post merger beta exhibits excess comovement with the acquiring firm. This suggests that the firm’s comovement is at least partly determined by its investors. We find that the excess comovement is significantly greater in cash...

Aggregate investment externalities and macroprudential regulation
Empirical evidence shows that banks tend to lend too much during booms, and too littleduring recessions. Thus, instead of dampening productivity shocks, the banking sectortends to exacerbate them, leading to excessive fluctuations of credit, output and assetprices. We propose a simple explanation for this dysfunctionality of credit markets. Thisexplanation relies on three ingredients...

Equilibrium implications of delegated asset management under benchmarking
Despite the enormous growth of the asset management industry during the pastdecades, little is known so far about the asset pricing implications of investmentintermediaries. Investment objectives of professional asset managers such as mutualfunds differ from those of private households. However, standard models of invest-ment theory do not address the distinction between direct...

Explaining the demand for structured financial products: survey and field experiment evidence
In many countries structured investment products are popular among retail investors.Weexplain the demand for these products using unique field data where we let subjects freely design their “favorite” structured product. Results suggest that the supply with capital protected products (guarantee certificates) might indeed be demand-driven. This does not seem to be the case for other...
