In this paper, I estimate the non-parametric optimal bond portfolio choice of a representative agent that acts optimally with respect to his/her expected utility one period forward, provided that he/she observes the ex ante liquidity signal. Using daily observations of zero-coupon Treasury and...

Using the Markowitz mean-variance portfolio optimization theory, researchers have shown that the traditional estimated return greatly overestimates the theoretical optimal return, especially when the dimension to sample size ratio p/n is large. Bai, Liu, and Wong (2009) propose a...

We introduce a copula-based dynamic model for multivariate processes of (non-negative) high-frequency trading variables revealing time-varying conditional variances and correlations. Modeling the variables’ conditional mean processes using a multiplicative error model we map the resulting...

To measure income inequality with right censored (topcoded) data, we propose multiple imputation for censored observations using draws from Generalized Beta of the Second Kind distributions to provide partially synthetic datasets analyzed using complete data methods. Estimation and inference...

Neither existing theory nor prior empirical work can tell us the impact of non-normality on required sample sizes for Student-t tests of the mean in U.S. stock returns. Prior empirical work and bounds from a modified Berry-Esseen theorem do suggest, however, that the answer should vary with...

Concentration is a single summary statistic driven by two opposing forces: the number of firms in a market and the evenness of their market shares. This paper introduces a generalized measure of concentration that allows researchers to vary the relative importance of each force. Using the...

Summary • Putin and Trump, leaders arguably with hostile powers. Their meeting holds significant importance in history, requiring scenario planning to structure long-term business relationships and a defense playground for both countries.• It will provide assurances; to the operating...

As the COVID-19 pandemic strained supply chains around the world a striking, and seeming contradictory, outcome became apparent: Surges in rates of hunger in consumers occurred simultaneously with surges in food surplus and purposeful disposal. To better understand the systemic origins of this...

Considerable public resources are devoted to the establishment and operation of business incubators (BIs), which are seen as catalysts for the promotion of entrepreneurship, innovation activities and regional development. Despite the vast amount of research that has focused on the outcomes or...
