title: Replication data for: Averting Catastrophes: The Strange Economics of Scylla and Charybdis

description: Faced with numerous potential catastrophesâ€”nuclear and bioterrorism, mega-viruses, climate change, and othersâ€”which should society attempt to avert? A policy to avert one catastrophe considered in isolation might be evaluated in cost-benefit terms. But because society faces multiple catastrophes, simple cost-benefit analysis fails: even if the benefit of averting each one exceeds the cost, we should not necessarily avert them all. We explore the policy interdependence of catastrophic events, and develop a rule for determining which catastrophes should be averted and which should not. (JEL D61, Q51, Q54)

title: Replication data for: How to Count Citations If You Must

description: Citation indices are regularly used to inform critical decisions about promotion, tenure, and the allocation of billions of research dollars. Nevertheless, most indices (e.g., the h-index) are motivated by intuition and rules of thumb, resulting in undesirable conclusions. In contrast, five natural properties lead us to a unique new index, the Euclidean index, that avoids several shortcomings of the h-index and its successors. The Euclidean index is simply the Euclidean length of an individual's citation list. Two empirical tests suggest that the Euclidean index outperforms the h-index in practice.

title: Replication data for: Which Entrepreneurs Are Coachable and Why?

description: Is coachability a usable concept for startups? Using a dataset on high-growth startups in a prominent university incubator, we show that firm characteristics do predict which firms are likely to follow advice but that these "coachable" firms are not more likely to achieve positive outcomes. The reason is that advice may be rejected either because the firm is stubborn and uncoachable, or because the firm possesses capabilities related to the advice which is hard for outsiders to observe.

title: Replication data for: Heterogeneous Scarring Effects of Full-Year Nonemployment

description: Drawing on administrative data from the Social Security Administration, we find that individuals that go through a long period of non-employment suffer large and long-term earnings losses (around 35-40 percent) compared to individuals with similar age and previous earnings histories. Importantly, these differences depend on past earnings, and are largest at the bottom and top of the earnings distribution. Focusing on workers that are employed 10 years after a period of long-term non-employment, we find much smaller earnings losses (8-10 percent). Furthermore, the large earnings losses of low-income individuals are almost entirely due to employment effects.

title: Replication data for: Returns to Education through Access to Higher-Paying Firms: Evidence from US Matched Employer-Employee Data

description: We use administrative US matched employer-employee data merged with detailed information on individuals' academic records to assess the extent to which returns to education are mediated by the sorting of workers across firms. We present three results. First, we confirm findings in the earlier literature of large pay differences across higher education degrees. Second, we show that up to one quarter of pay premiums for higher degrees are explained by between-firm pay differences. Third, higher degrees are associated with greater representation at the best-paying firms. We conclude that employer heterogeneity is an important factor in mediating the returns to education.

title: Replication data for: Wage Inequality and Firm Growth

description: We discuss firm-level evidence based on UK data showing that within-firm pay inequality--wage differentials between top- and bottom-level jobs--increases with firm size. Moreover, within-firm pay inequality rises as firms grow larger over time. Lastly, using wage data from 15 developed countries, we document a positive association between aggregate wage inequality at the country level and growth by the largest firms in the country. We conclude that part of what may be perceived as a global trend toward more wage inequality may be driven by an increase in the size of the largest firms in the economy.

title: Replication data for: Return of the Solow Paradox? IT, Productivity, and Employment in US Manufacturing

description: An increasingly influential "technological-discontinuity" paradigm suggests that IT-induced technological changes are rapidly raising productivity while making workers redundant. This paper explores the evidence for this view among the IT-using US manufacturing industries. There is some limited support for more rapid productivity growth in IT-intensive industries depending on the exact measures, though not since the late 1990s. Most challenging to this paradigm, and to our expectations, is that output contracts in IT-intensive industries relative to the rest of manufacturing. Productivity increases, when detectable, result from the even faster declines in employment.

title: Replication data for: Ability-Tracking, Instructional Time, and Better Pedagogy: The Effect of Double-Dose Algebra on Student Achievement

description: This paper provides new evidence on tracking by studying an innovative curriculum implemented by Chicago Public Schools (CPS). In 2003, CPS enacted a double-dose algebra policy requiring 9th grade students with 8th grade math scores below the national median to take two periods of algebra instead of one. This policy led schools to sort students into algebra classes by math ability, so that tracking increased in all algebra classes. We show that double-dosed students are exposed to a much lower-skilled group of peers in their algebra classes but nonetheless benefit substantially from the additional instructional time and improved pedagogy.

title: Replication data for: Using School Choice Lotteries to Test Measures of School Effectiveness

description: Value-added models (VAMs) are increasingly used to measure school effectiveness. Yet, random variation in school attendance is necessary to test the validity of VAMs and to guide the selection of models for measuring causal effects of schools. In this paper, I use random assignment from a public school choice lottery to test the predictive power of VAM specifications. In VAMs with minimal controls and two or more years of prior data, I fail to reject the hypothesis that school effects are unbiased. Overall, many commonly used VAMs are accurate predictors of student achievement gains.

title: Replication data for: Gender and Race Heterogeneity: The Impact of Students with Limited English on Native Students' Performance

description: Recent evidence suggests that exposure to a larger share of Limited English (LE) students is associated with a slight decline in performance for students at the top of the achievement distribution. In this paper we explore whether LE peer effects differ by gender and race. Utilizing school-by-year fixed effect methods that allow us to address possible endogeneity with respect to the schools students attend, we find evidence of heterogeneous peer effects of LE students on natives. Specifically, we find no LE student peer effects on females' achievement in math and reading but significant negative effects on males and black students.

title: Replication data for: The Wind of Change: Maritime Technology, Trade, and Economic Development

description: The 1870-1913 period marked the birth of the first era of trade globalization. How did this tremendous increase in trade affect economic development? This work isolates a causality channel by exploiting the fact that the introduction of the steamship in the shipping industry produced an asymmetric change in trade distances among countries. Before this invention, trade routes depended on wind patterns. The steamship reduced shipping costs and time in a disproportionate manner across countries and trade routes. Using this source of variation and novel data on shipping, trade, and development, I find that (i) the adoption of the steamship had a major impact on patterns of trade worldwide; (ii) only a small number of countries, characterized by more inclusive institutions, benefited from trade integration; and (iii) globalization was the major driver of the economic divergence between the rich and the poor portions of the world in the years 1850-1900.

title: Replication data for: You Owe Me

description: In business and politics, gifts are often aimed at influencing the recipient at the expense of third parties. In an experimental study, which removes informational and incentive confounds, subjects strongly respond to small gifts even though they understand the gift giver's intention. Our findings question existing models of social preferences. They point to anthropological and sociological theories about gifts creating an obligation to reciprocate. We capture these effects in a simple extension of existing models. We show that common policy responses (disclosure, size limits) may be ineffective, consistent with our model. Financial incentives are effective but can backfire.

title: Replication data for: Trumping Norms: Lab Evidence on Aggressive Communication before and after the 2016 US Presidential Election

description: This paper provides evidence from a negotiation experiment that the 2016 US presidential election of Donald Trump had a profound impact on individual behavior in the lab. Using a Battle of the Sexes game with unstructured communication, we find that post-election individuals are less cooperative in general, more likely to use adversarial negotiation strategies, and less likely to reach an agreement. Furthermore, this is particularly driven by men acting more aggressively toward women. Our results are robust to controlling for sample selection. These results suggest that Trump's election may have disrupted community norms around civility and chivalry.

title: Replication data for: The Future of US Economic Growth

description: Modern growth theory suggests that more than three-quarters of growth since 1950 reflects rising educational attainment and research intensity. As these transition dynamics fade, US economic growth is likely to slow at some point. However, the rise of China, India, and other emerging economies may allow another few decades of rapid growth in world researchers. Finally, and more speculatively, the shape of the idea production function introduces a fundamental uncertainty into the future of growth. For example, the possibility that artificial intelligence will allow machines to replace workers to some extent could lead to higher growth in the future.

title: Replication data for: Presidents and the US Economy: An Econometric Exploration

description: The US economy has performed better when the president of the United States is a Democrat rather than a Republican, almost regardless of how one measures performance. For many measures, including real GDP growth (our focus), the performance gap is large and significant. This paper asks why. The answer is not found in technical time series matters nor in systematically more expansionary monetary or fiscal policy under Democrats. Rather, it appears that the Democratic edge stems mainly from more benign oil shocks, superior total factor productivity (TFP) performance, a more favorable international environment, and perhaps more optimistic consumer expectations about the near-term future.

title: Replication data for: Exporter Dynamics and Partial-Year Effects

description: Two identical firms who start exporting in different months, one each in January and December, will report dramatically different exports for the first calendar year. This partial-year effect biases down first-year export levels and biases up first-year export growth rates. For Peruvian exporters, the partial-year bias is large: first-year export levels are understated by 54 percent and the first-year growth rate is overstated by 112 percentage points. Correcting the partial-year effect dramatically reduces first-year export growth rates, raises initial export levels, and almost doubles the contribution of net firm entry and exit to overall export growth.
