Enforcement Problems and Secondary Markets

Broner, Fernando A. - 2007

There is a large and growing literature that studies the effects of weak enforcement institutions on economic performance.

Financial Super-Markets : Size Matters for Asset Trade

Martin, Philippe - 2001

We introduce a new theoretical framework to analyze imperfectly competitive financial markets and trade in assets in an international context. We present a two-country macroeconomic model in which agents are risk averse, assets are imperfect substitutes, the number of financial assets is...

Efficiently Inefficient Markets for Assets and Asset Management

Gârleanu, Nicolae B. - 2015

We consider a model where investors can invest directly or search for an asset manager, information about assets is costly, and managers charge an endogenous fee. The efficiency of asset prices is linked to the efficiency of the asset management market: if investors can find managers more...

The Inefficient Markets Hypothesis : Why Financial Markets Do Not Work Well in the Real World

Farmer, Roger E.A. - 2012

Existing literature continues to be unable to offer a convincing explanation for the volatility of the stochastic discount factor in real world data. Our work provides such an explanation. We do not rely on frictions, market in completeness or transactions costs of any kind. Instead, we modify a...

Counterparty Risk Externality : Centralized Versus Over-the-counter Markets

Acharya, Viral V. - 2011

We model the opacity of over-the-counter (OTC) markets in a setup where agents share risks, but have incentives to default and their financial positions are not mutually observable. We show that this setup results in excess "leverage" in that parties take on short OTC positions that lead to...

Cointegration and Tests of Present Value Models

Campbell, John Y. - 1986

In a model where a variable Y[sub t] is proportional to the present value, with constant discount rate, of expected future values of a variable y[sub t] the "spread" S[sub t]= Y[sub t] - [theta sub t] will be stationary for some [theta] whether or not y[sub t]must be differenced to induce...

Do Asset Prices Reflect Fundamentals? Freshly Squeezed Evidence from the OJ Market

Boudoukh, Jacob - 2003

We show that when theory clearly identifies the fundamental, i.e., at temperatures …-thirds of the entire winter return variability occurs on these days. Moreover, when theory suggests no such relation, i.e., at … is good news for the theory and for market efficiency, not bad news. In terms of residual FCOJ return volatility, we also …

Equity market liberalizations as country IPOs

Martell, Rodolfo - 2003

Equity market liberalizations are like IPOs, but they are IPOs of a country's stock market rather than of individual firms. Both are endogenous events whose benefits are limited by poor investor protection, agency costs, and information asymmetries. As for stock prices following an IPO, there...
