This paper documents that political factors can be linked to the part of stock prices that cannot be explained by the standard present value models. The non-fundamental component of stock market index appears to be significantly influenced by the political orientation of the president and his approval rating, election cycle and military conflicts. The findings presented here indicate that there...

Abstract The aim of this paper is to analyze the long-lasting dynamic relationship between credit default swap (CDS) premia and government bond spreads (GBS), with regard sovereign risk. practical focus evaluate whether CDS market effectively leading or lagging in risk price discovery process during last decade monetary easing. analysis extends all “sensitive” countries Eurozone, so-called “PII...

In this paper we extend the results of recent studies on the existence of equilibrium in finite dimensional asset markets for both bounded and unbounded economies. We do not assume that the individual’s preferences are complete or transitive. Our existence theorems for asset markets allow for short selling. We shall also show that the equilibrium achieves a constrained core within the same fram...

We estimate various SVAR models for the US in order to assess the importance of fundamental shocks in explaining stock price movements. The results show that models using real activity variables place more weight on fundamental shocks than models using dividends or earnings. However, according to all models fundamental shocks became substantially less important during the period 1982-2002 if co...

In this paper, we use stochastic dynamic programming to study the intertemporal consumption and portfolio choice of an infinitely lived agent who faces a constant opportunity set and a borrowing constraint. We show that, under general assumptions on the agent's utility function, optimal policies exist and can be expressed as feedback functions of current wealth. We describe these policies in de...

A major obstacle for research in international asset pricing and corporate finance has been a lack of reliable and publicly available data on international common risk factors and portfolios. To address this gap, we provide a step-by-step description of how appropriately screened data from Thomson Reuters Datastream and Thomson Reuters Worldscope can be used to construct high-quality systematic...

The Hippo pathway is an evolutionarily conserved kinase cascade involved in the control of tissue homeostasis, cellular differentiation, proliferation, and organ size, regulated by cell-cell contact, apical cell polarity, mechanical signals. Miss-regulation this can lead to cancer. acts through inhibition transcriptional coactivators YAP TAZ phosphorylation. Among various signaling mechanisms c...

We present a simple example where the use of σ-algebras as a model of information leads to a paradoxical conclusion: a decision maker prefers less information to more. We then explain that the problem arises because the use of σ-algebras as the informational content of a signal is inadequate. We provide a characterization of the different models of information in the literature in terms of Blac...

The negative relationship between market P/E ratios and government bond yields seems to have become conventional wisdom among practitioners. Both (limited) empirical evidence and a (misleading) suggestion that the model originated in the Fed are used to support the model’s plausibility. The evidence in this note, from 20 international markets, seriously questions the wide acceptance and use of ...

Signaling through the heterotrimeric G protein, G12, via Rho induces a striking increase in breast cancer cell invasion. In this study, evidence is provided that the c-Jun NH(2)-terminal kinase (JNK) is a key downstream effector of G12 on this pathway. Expression of constitutively-active Gα12 or activation of G12 signaling by thrombin leads to increased JNK and c-Jun phosphorylation. Pharmacolo...
