This paper improves upon the existing literature surrounding the production order quantity inventory model in which unit cost and daily production are assumed to be constant. By including economies of scale into the model, we examine its impact on production order quantity and total cost. The...

Land subsidence created by underground coal mining has a critical influence on the structure and function of ecosystems in mining areas. However, knowledge of the aquatic bacterial community structure and interspecies interactions in subsidence lake is still limited. To address this, we...

We propose a new measure of portfolio activity, the Modified Turnover, which represents the portion of the portfolio that the manager changes from one quarter to the next. Compared with the traditional turnover, our Modified Turnover measure relies on portfolio holdings and takes into account...

Interest in socially responsible investing (SRI) has skyrocketed within the mutual fund industry. Central to this development is whether SRI funds underperform conventional funds. Using a novel approach, we decompose mutual fund portfolios into socially responsible (green) and non-socially...

The tournament hypothesis of Brown et al. (1996) conjectures that mutual funds with a below average performance over the first half of the year tend to increase their risk in the second half of the year. Schwarz (2012) argues that the methodologies that have been used to test this hypothesis are...

The tournament hypothesis of Brown et al. (1996) posits that managers of poorly performing funds actively increase portfolio risk in the second half of the year. At the same time, it is a well-established stylized fact that stock returns and the subsequent return standard deviation are...

An emerging literature has shown that investors are sensitive to mutual fund names. Using a sample of US equity funds over the period 1993-2017, we provide evidence that funds with a name closer to the family's name attract more flows and display a stronger performance-flow relationship. We also...

In this paper, we provide an in-depth analysis of the performance of newly launched mutual funds. We highlight a positive connection between past performance of families and subsequent new fund performance among top deciles. Moreover, we present a new performance measure for newly launched funds...

This paper examines the relationship between the volatilities of equity indexes returns and FX rates for a set of emerging countries. We study the sensitivity of sector indexes volatility to FX rates volatility of local currencies with respect to the U.S. Dollar, the British Pound, and the...
