A Linear Pricing Rule is established for the No Strong Arbitrage Principle (NSAP) in a finite state, single period asset pricing model. The (NSAP) condition is a statement about the inconsistency of a particular system of linear inequalities. The novelty here lies in the use of the...

We present a microfounded New Keynesian model that features financial vulnerabilities. Financial intermediaries' occasionally binding value-at-risk constraints give rise to variation in the pricing of risk that generates time-varying risk in the conditional mean and volatility of the output gap....

We derive invariance relationships in a dynamic, infinite-horizon, equilibrium model of adverse selection with risk-neutral informed traders, noise traders, market makers, and with endogenous information production. The model solution depends on two state variables: stock price and...

We survey the nascent literature on machine learning in the study of financial markets. We highlight the best examples of what this line of research has to offer and recommend promising directions for future research. This survey is designed for both financial economists interested in grasping...

Earlier studies in the finance literature show that macroeconomic fundamentals can predict excess bond returns. We employ a multi-level factor model to estimate global and sectoral factors separately and show that (i)the real factors possess most important predictive power existing in the panel;...

We investigate the relevance of the characteristics of the Ministers of Finance in influencing, via their implementation of fiscal policies, the developments, in stock returns, sovereign yields and fiscal outcomes. For a panel of 27 EU countries, covering the period 1980-2012, we find that...

Empirical evidence has demonstrated that there are bubbles in the prices of financial assets, in other words, when assets are traded at prices either above or below their fundamental value. With this in mind, it is desirable to seek answers to the following questions: What reasons are given by...

It is generally accepted that excessive exuberance or gloom in investor sentiment contributes to booms and crashes in asset prices but, because of its complex interaction with other aspects of the valuation process, these effects are not easy to identify with statistical confidence and this...

We show that immediate and delayed abnormal returns following earnings announcement surprises differ across market states. Immediate abnormal returns are more sensitive to earnings surprises in down markets, while delayed abnormal returns are less sensitive; underreaction is attenuated in down...

The main aim of the thesis is to formulate a concept of liquidity risk and to incorporate liquidity risk in market risk measurement. We first review two types of liquidity risk and the relation between liquidity risk and market risk. To achieve our aim, we use a new framework of portfolio theory...
