4/21/2021 — This article introduces structured machine learning regressions for high-dimensional time series data potentially sampled at different frequencies. The sparse-group LASSO estimator can take advantage of such time series data structures and outperforms the unstructured LASSO. We establish oracle inequalities for the sparse-group LASSO estimator within a framework that allows for the mixing processes and recognizes that the financial and the macroeconomic data may have heavier than exponential tails.

3/30/2021 — To what extent do consumers boycott in response to corporate tax activities? Anecdotes suggest potential consumer backlash is a meaningful deterrent to corporate tax planning, and the tax literature has developed expectations that these boycotts happen. But empirical evidence on their existence and impact is limited. We undertake a comprehensive study to examine how consumers’ purchase behavior relates to corporate tax activities, triangulating across several designs, samples, and measures.

3/22/2021 — t that the currency denomination of the debt of large firms in developed countries is strongly associated with the geographical distribution of their sales. Furthermore, those firms exhibit significant home currency bias and international currency bias in debt issuance: controlling for the geography of sales, they borrow more in their home currency and the two most traded currencies, the US dollar and the euro.

3/4/2021 — We measure the racial/ethnic densities (RAEDs) of executives in a random sample of 523 US publicly traded companies and the S&P 500®. When we calibrate the RAEDs of executives as a whole against the RAEDs of the 2019 US population, we find that American Indians/Alaska Natives, Blacks and Hispanics are underrepresented and Whites are overrepresented. However, when we calibrate executive RAEDs against a benchmark that seeks to take into account key features of the demand for and supply of proto-executive talent, namely the RAEDs of the cohorts of students graduating with a bachelor’s degree from the broad New York Times 2017 list of the top 100 US four-year colleges and universities, matched to executives’ BA/BS graduation years, mostly different and at times opposite findings obtain.

3/1/2021 — This paper examines the spillover effects of U.S. unconventional monetary policy (UMP) on emerging market capital flows and asset prices. Affine term structure model estimates show that U.S. monetary policy shocks, identified with high-frequency Treasury futures data, represent revisions to expected short-term yields and term premia, especially during the UMP period. The policy shocks exhibit sizable effects on U.S. holdings of emerging market assets. These effects disproportionately manifest through valuation changes versus physical flows, are more pronounced for equity relative to bond markets, and are asymmetric between the quantitative easing and tapering periods, with flows more important during the unwinding.

2/25/2021 — We propose and test a framework of private information acquisition and decision timing for asset allocators hiring outside investment managers. Using unique data on due diligence interactions between an institutional allocator and 860 hedge fund managers, we find that the production of private information complements public information. The allocator strategically chooses how much proprietary information to collect, reducing due diligence time by 18 months and improving outcomes. Selected funds outperform unselected funds by 9% over 20 months. The outperformance relates to the allocator learning about fund return-to-scale constraints and manager skill before other investors.

We are especially concerned about the premature re-opening of schools in impoverished and flood-prone urban and rural environments.

2/10/2021 — The slope carry takes a long (short) position in the long-term bonds of countries with steeper (flatter) yield curves. The traditional carry takes a long (short) position in countries with high (low) short-term rates. We document that: (i) the slope carry return is slightly negative (strongly positive) in the pre (post) 2008 period, whereas it is concealed over longer samples; (ii) the traditional carry return is lower post-2008; and (iii) expected global growth and inflation declined post-2008.

2/6/2021 — We axiomatize subjective probabilities on finite domains without requiring richness in the outcome space or restrictions on risk preference through event exchangeability, defined in Chew and Sagi (2006), which was implicit in the prior literature (Savage, 1954; Machina and Schmeidler, 1992; Grant, 1995). We characterize the unique subjective probability representing the underlying exchangeability relation.

2/1/2021 — This paper presents an innovative approach to extract Volatility Factors which predict the VIX, the S&P500 Realized Volatility (RV) and the Variance Risk Premium (VRP). The approach is innovative along two different dimensions, namely: (1) we extract Volatility Factors from panels of filtered volatilities — in particular large panels of univariate ARCH-type models and propose methods to estimate common Volatility Factors in the presence of estimation error and (2) we price equity volatility risk using factors which go beyond the equity class namely Volatility Factors extracted from panels of volatilities of short-run funding spreads.

1/29/2021 — People of color are overrepresented relative to their shares of the total population in coronavirus infections, hospitalizations, and deaths. The same is true for people living in over-crowded multigenerational households. Because people of color are more likely to live in multigenerational households than are Whites, the pandemic is having a double whammy effect in communities of color throughout the U.S.

1/28/2021 — There are bipartisan Medicare payment proposals that would reduce Medicare payments included in previous Obama and Trump budgets that could go a long way to filling the budget shortfall.

1/22/2021 — Considerable scholarly analysis and media attention has documented the racially disparate impact of coronavirus infections, hospitalizations, and deaths. Constituting 13 percent of the general population, Blacks reportedly account for 25 percent of those that have tested positive and 39 percent of the COVID-related deaths in the United States.

1/19/2021 — Background: Influenza imposes heavy societal costs through healthcare expenditures, missed days of work, and numerous hospitalizations each year. Considering these costs, the healthcare and behavioral science literature offers suggestions on increasing demand for flu vaccinations. And yet, the adult flu vaccination rate fluctuated between 37% and 46% between 2010 and 2019.Aim: Although a demand-side approach represents one viable strategy, an operations management approach would also highlight the need to consider a supply-side approach. In this paper, we investigate how to improve clinic vaccination rates by altering provider behavior.

To shed light on this question, we build a novel, comprehensive dataset. Firms without a history of debt financing exhibit limited exposure to a systemic event. For firms that rely on external debt financing, their exposures are mainly driven by pre-existing connections to these central financial institutions.

11/3/2020 — Adopting a justice enactment perspective, we explore managers' consistent versus inconsistent application of existing rules in allocation decisions. We propose that when managers form friendship relationships with their employees, they are likely to experience greater tensions when fulfilling their managerial duties as resource allocators. On the one hand, managers may wish to deviate from the rules to benefit an employee who is also a friend. On the other hand, benefiting one employee (but not others) might lead to tensions in managers' friendships with other employees.

10/27/2020 — As the nature of work has become more service-oriented, knowledge-intensive, and rapidly changing, people—be they workers or customers—have become more central to operational processes and have impacted operational outcomes in novel and perhaps more fundamental ways. Research in people-centric operations (PCO) studies how people affect the performance of operational processes. In this OM Forum, we define PCO as an area of study, offer a categorization scheme to take stock of where the field has allocated its attention to date, and offer our thoughts on promising directions for future research.

10/25/2020 — The idea that new ventures are simple mimetic reflections of the organizational practices of existing organizations contradicts the recognized importance of organizational diversity for innovation. There is an inherent contradiction in the literature between the persistence implied by the inheritance of practices from prior employment, and the experimentation prevalent in the organizational practices contributed by new organizations. This paper first accounts for mechanisms that may drive heritage of practices from parent organizations to their spawns.

In each period, the company observes the customers' consumption as well as high-dimensional features on customer characteristics and exogenous factors. A distinctive element of our work is that these features exhibit three types of heterogeneity—over time, customers, or both. Based on the consumption and feature observations, the company can dynamically adjust the retail electricity price at the customer level.

This small cost savings needs to be weighed against the potentially large costs to investors and others created by eliminating a public disclosure that they heavily use.
