A new integral for capacities, different from the Choquet integral, is introduced and characterized. The main feature of the new integral is concavity, which might be interpreted as uncertainty aversion. The integral is then extended to fuzzy capacities, which assign subjective expected values...

The paper develops a theoretical model showing a mutual relationship between corruption and capital account restrictions. According to the model, higher corruption induces stricter restrictions and vice versa. We test the model using panel data for 112 countries over the period 1984-2002 and...

Investors systematically deviate from rationality when making financial decisions, yet the mechanisms responsible for these deviations have not been identified. Using event-related fMRI, we examined whether anticipatory neural activity would predict optimal and suboptimal choices in a financial...

A man is a key subject of economics and economic theory. “A man is irrational” - this opinion can be made from Allais paradox, risk aversion and other well-known fundamental problems. For a long time, this opinion was a barrier to proper solution of these problems and the development of the...

The need to develop securities market has, following the recent international financial crises, increasingly attracted the attention of national and international policy makers. Never before have developed and developing countries shared such a strong interest in ensuring the stable growth of...

This paper examines a decision-making problem of rational agents with risk averse utilities in the financial market both in statics and in dynamics. In the financial market there are two securities, one risky security and one riskless bond, and a continuum of investors with heterogeneous...

We examine the optimal consumption and portfolio choice of an investor having an initial wealth endowment and an uncertain stream of income from non-traded assets. The income stream is not spanned by traded assets, and the investor is not allowed to borrow against future income, so the financial...

This paper focuses on Stochastic Dominance (SD) efficiency in a finite empirical panel data. We analytically characterize the sets of unsorted time series that dominate a given evaluated distribution by the First, Second, and Third order SD. Using these insights, we develop simple Linear...

This paper analyses a temporary financial market equilibrium by considering a two-period model of asset pricing with s securities, one riskless bond, and a continuum of heterogeneous agents with different preferences, endowments, and beliefs. Investors' objectives are to maximize the expected...
