Since the early 1990s an unprecedented process of consolidation has taken place in the banking sector in most industrialised countries raising concern of policymakers that it may reduce access to credit for the small business sector. While most of the existing empirical studies have focused on...

We prove that high simulated performance is easily achievable after backtesting a relatively small number of alternative strategy configurations, a practice we denote “backtest overfitting”. The higher the number of configurations tried, the greater is the probability that the backtest is...

In this paper I test for and model volatility jumps for the General Index (GD) of the Athens Stock Exchange (ASE), expanding the previous literature on the ASE in various ways. Using intraday data I first construct various state-of-the-art realized volatility estimators which I then use in...

This is the first study of corporate-bond mutual fund performance that examines detailed security-level holdings and returns. The new database allows us to decompose the costs and benefits of active management. In contrast to prior research on equity funds that shows evidence of stock-selection...

Using 1994–2009 data, we find that All-American (AA) analysts' buy and sell portfolio alphas significantly exceed those of non-AAs by up to 7% per annum after risk-adjustments for investors with advance access to analyst recommendations. For investors without such access, top-rank AAs still...

Present paper shows that credit regarding job creation is ineffective in the 2000s, while it was effective in 1980s and 1990s. This paper attempts to support the view of (Bouis et al., 2013), that recently growth is sluggish, in spite of the massive monetary stimulus. Further, it will support...

Using 1994-2009 data, we find that All-American (AA) analysts' buy and sell portfolio alphas significantly exceed those of non-AAs by up to 0.6% per month after risk-adjustments for investors with advance access to analyst recommendations. For investors without such access, top-rank AAs still...

Empirical evidence shows that, in equity options markets, the slope of the skew is largely independent of the volatility level. Single-factor stochastic volatility models are not flexible enough to account for the stochastic behavior of the skew. On the other hand, multifactor stochastic...

The paper examined the interest rate operations and processes in Nigeria and examined the role of financial development in incentivizing central bank monetary policies from the monetary policy rate to the money market rates, lending rates, and deposit rates. The analysis covered the period from...

Using 1994-2009 data, we document that All-American (AA) analysts' buy and sell recommendations outperform those of non-AAs by over 7% per annum after risk-adjustments. This performance differential exists both before and after AAs are elected, does not exhibit long-run reversal, and is not...
