This study on the implementation efficiency of the HIV/AIDS national response in Colombia seeks to examine how it has been implemented -- whether it has been done according to the available evidence about the epidemic and as the response was originally planned. The study approaches three...

One of the major differences between markets that follow a “sharing economy” paradigm and traditional two-sided markets is that the supply side in the sharing economy often includes individual nonprofessional decision makers, in addition to firms and professional agents. Using a data set of...

We study the effects of the introduction of cross-channel functionalities on the overall sales dispersion of retailers and the implications of these effects for inventory management. To do that, we analyze data from a leading U.S. retailer who introduced a “ship-to-store” (STS) functionality...

The co-movement of US sovereign rates suggests a long-run equilibrium relationship.Traditional cointegrated systems need to assume that interest rates are unit roots and thus implying non-stationary and non-mean-reverting dynamics. We postulate and estimate a fractional cointegrated model...

Using a detailed dataset from the U.S. automotive industry, we empirically study the benefits and costs of maintaining a broader product line. Consistently with theoretical predictions, we find a positive association between product line breadth and both market share and unit production costs....

We provide a new measure of sovereign country risk exposure to global sovereign tail risk (SCRE) based on information incorporated in 5-year sovereign CDS spreads. Our panel regressions with quarterly data from 53 countries show that macro risks have strong explanatory power for SCRE. After...

We propose a novel methodology to characterize the investor decision making process. By drawing logical paths in a structural equation model (SEM) framework, we uncover the role of a latent financial risk index that is simultaneously shaping the dynamics of different financial asset prices. Our...

We reassess one of the major puzzles in international macroeconomics, namely the equity home bias puzzle, to shed some light on how it is affected by financial leverage. As corporate debt is generally key to employment, the analysis can provide interesting insights to the mooted argument...

The estimates of the U.S. term premium crucially depend upon the ex-ante decision on whether the short-term rate is either an I(0) or an I(1) process. In this paper we estimate a fractionally integrated (I(d)) model which simultaneously determines both the order of integration of the short-term...
