This paper uses a risk-shifting model to analyze policy responses asset price booms. We show risk shifting leads inefficient and credit booms in which prices can exceed fundamentals. However, the inefficiencies associated with arise independently of whether is bubble. Given evidence shifting, policymakers may not need determine if assets are bubbles justify intervention. then that some main can...

Static and discrete time pricing operators for two price economies are reviewed and then generalized to the continuous time setting of an underlying Hunt process. The continuous time operators define nonlinear partial integrodifferential equations that are solved numerically for the three valuations of bid, ask and expectation. The operators employ concave distortions by inducing a probability ...

Abstract This paper highlights the adverse consequences of sluggish credit rating updates in creating information efficiency distortions and investment anomalies. We first document significant default swap (CDS) return momentum yielding 7.1% per year. further show that cross-market strategies based on past CDS performance generates an alpha 10.3% year stocks 7.3% bonds. These effects are strong...

Abstract This paper explores the impact of product market competition on positive relation between labor mobility (LM) and future returns. We develop a production-based model formalize intuition that low exposure to systematic risk in concentrated industry limits LM’s amplifying effect operating leverage. Therefore, predicts stronger LM expected returns for firms competitive industries. Consist...

explanation relation between risk and return and capital asset pricing are concepts which is appointed as dominator and major paradigms in capital markets. so far as after offering capm by sharp & lintner, this model has been revised and criticized frequently. in this paper another version of capm has been tested versus traditional capm in tehran stock exchange. this version of capm measures se...

The share price represents the company's value on market; buyers and sellers establish based quantity of demand supply shares. This research looks at how market capitalization, trading volume, BV, DER are used to analyze variations. aims understand investor behavior in fluctuating situations. method is multiple linear regression, data collection secondary data. study's results indicate a relati...

in this paper using catastrophe theory, we investigate non-smooth changes in tehran stock exchange. stock market crashes bring not only panic among investors, but also in deeper market lead to recession and decrease in consumer's confidence. as catastrophe theory is strong tool in explaining nonlinear phenomena, by applying stochastic cusp catastrophe model we examine sudden change in tehr...

This survey discusses behavioral and experimental macroeconomics, emphasizing a complex systems perspective. The economy consists of boundedly rational heterogeneous agents who do not fully understand their environment use simple decision heuristics. Central to our is the question under which conditions macro-system interacting may or coordinate on equilibrium outcome. A general finding that po...

The present paper thoroughly explores second-best efficient allocations in an adverse selection insurance economy. We start from a natural extension of the classical model, assuming less than perfect risk perceptions. We propose first and second welfare theorems, by means of which we describe efficiencyenhancing policies. Notions of weak and strong adverse selection are promising for interpreti...
