REVISION: A Regulator's Exercise of Career Option to Quit and Join a Regulated Firm's Management with Applications to Financial Institutions

February 16, 2017 Comments (0)

Among the issues raised during post-mortem of the financial crisis of 2008 is regulatory capture and revolving doors for regulators and political operatives transitioning to lobbying firms or financial firms they once regulated. Several papers claim that this facilitated lax enforcement by regulators, and excessive risk taking by financial firms – key factors that led to the crisis. This paper fills a gap in the literature by posing the revolving door hypothesis in the context of managerial...

New: Expected Utility Theory and Inner and Outer Measures of Loss Aversion

May 5, 2016 Comments (0)

We introduce a weak rank dependent utility (RDU) model, with one extra parameter compared to the canonical expected utility (EUT) model, which makes many of the same predictions as cumulative prospect theory (CPT). The model extends a set of nonconvex preferences to its maximal inner convex subset, satisfies stochastic dominance principles, resolves the Allais paradox, predicts CPT fourfold pattern of risk attitudes, and characterizes reference dependent preferences. Unlike extant RDU models...

REVISION: Diffusing Explosive Portfolio Performance Evaluation of High Frequency Traders

September 26, 2015 Comments (0)

Several analysts report explosive annualized Sharpe Ratios (ASRs) for investment portfolio performance evaluation of high frequency traders (HFTers) ranging from 4.3 to 5,000. This suggests that the profitability of HFT is much higher than that of other actively managed portfolios. In highly competitive financial markets where ASRs for experienced traders are often much less than 2, those numbers imply that the ASR for HFT is misspecified. Thus, HFT performance is incomparable to the...

REVISION: Bankruptcy Risk Induced by Career Concerns of Regulators

January 1, 2014 Comments (0)

We introduce a model in which a regulator employs mechanism design to embed her human capital beta signal(s) in a firm’s capital structure, in order to enhance the value of her post career change indexed executive stock option contract with the firm. We prove that the agency cost of this revolving door behavior increases the firm’s financial leverage, bankruptcy risk, and affects estimation of firm value at risk (VaR).

REVISION: The Risk Premium for Minority Banks Altruistic Portfolios in Underserved Communities

December 31, 2013 Comments (0)

Motivated by behavioural asset pricing theory, we extend Vasicek (1977, 2002) factor pricing models to a statistical risk accounting model to characterize the compensating risk premium required to sustain minority banks’ (MBs) altruistic motive to provide credit in underserved communities. Our model predicts that increased bank capitalization, and brokered deposit (BD) exceptions, compensate risk when the incremental internal rate of return they induce is negatively correlated with the...

New: Group Representations for Decision Making under Risk and Uncertainty

December 21, 2012 Comments (0)

This paper extends decision making under risk and uncertainty to group theory via representations of invariant behavioural space for prospect theory. First, we predict that canonical specifications for value functions, probability weighting functions, and stochastic choice maps are homomorphic. Second, we derive a continuous singular matrix operator T for affine transformation of a vector space of skewed S-shape value functions V isomorphic to a vector spaceW of inverted S-shaped probability wei
