I provide evidence on the causal effects of a student's relative socioeconomic status during high school on their mental health and human capital development. Leveraging data from representative US high schools, I utilize between-cohort differences in the distributions of socioeconomic status...

It is often desired to rank different populations according to the value of some feature of each population. For example, it may be desired to rank neighborhoods according to some measure of intergenerational mobility or countries according to some measure of academic achievement. These rankings...

Performance ranks introduce a trade-off for workers. They have to choose between signaling high productivity or signaling social compatibility to peers. Using a long-term experiment at a sweater factory, this paper disentangles the incentives underlying performance ranks. Treated workers receive...

In recent years there has been a plethora of empirical papers by economists concerning the effects of academic rank in school or college on subsequent outcomes of students. We review this recent literature, describing the difficult identification and measurement issues, the assumptions and...

We prove that in a market where agents rank objects independently and uniformly at random, there exists an assignment of objects to agents with a constant average rank (i.e., an average rank independent of the market size). The proof builds on techniques from random graph theory and the FKG...

For example, it may be desired to rank neighborhoods according to some measure of intergenerational mobility or countries according to some measure of academic achievement. These rankings...

Economists are obsessed with rankings of institutions, journals, or scholars according to the value of some feature of interest. These rankings are invariably computed using estimates rather than the true values of such features. As a result, there may be considerable uncertainty concerning the...

Nowadays, university rankings are used to assess all aspects of universities. Due to the impact of university rankings on assessing the performance of universities, this research aims to explore university rankings in depth. University rankings are considered contributors to assessing university...

Due to the non-normality of stock returns, nonparametric rank tests are gaining accceptance relative to parametric tests in financial economics event studies. In rank tests, financial assets’ multiple day cumulative abnormal returns (CARs) are replaced by cumulated ranks. This paper proposes...

This paper investigates the effect of grouping students by prior achievement into different classes (or schools) in settings where students are competing for admission to programs offering only a limited number of places. We first develop a model that identifies the conditions under which the...

I investigate the paradoxes associated with the Fédération Internationale de Football Association (FIFA) point-based ranking of national soccer teams. The ranking has been plagued with paradoxes that incentivize teams to avoid playing friendly matches, i.e., matches that are not part of any...

We propose an innovative use of the information provided by the Leiden Rankings (LR). Although LR only consider research output of major universities reported in Web of Science, statistical analysis of LRs combined with network mapping can reveal the complexity of research performance...

Most research on Initial Public Offering (IPO) focuses on the financial aspects of a company; previous research on corporate governance tended to focus on factors that influence the company proceeding with IPO. Few researchers studied the aspect of leadership using corporate governance as means...

Seeking the greatest possible return on long-term investments, investors naturally seek equities of the best-performing companies that fit their investment timeframe. Long-term investment success rests on selecting the best companies, which requires a challenging analysis reviewing voluminous...

Combining data on around four million respondents from the Gallup World Poll and the US Daily Tracker Poll we rank 164 countries, the 50 states of the United States and the District of Colombia on eight wellbeing measures. These are four positive affect measures - life satisfaction, enjoyment,...

This paper provides a simple theoretical framework to evaluate the effect of key parameters of ranking algorithms, namely popularity and personalization parameters, on measures of platform engagement, misinformation and polarization. The results show that an increase in the weight assigned to...

The paper outlines the most important shipbuilding strategies in Romania that would allow this industry to increase its performance to be competitive. The research is mainly based on the collection of information from experts in the field from ANCONAV (Romanian Shipbuilders Association),...

U.S. News ranks law school specialty programs solely on reputation. A faculty member teaching in a specialty area at each school is asked to assess their area at other ABA accredited schools. In 2021, U.S. News added four more specialty programs: business/corporate law; constitutional law;...

We improve on the Instrumented Principal Component Analysis (IPCA) model developed in Kelly, Pruitt and Su (2019) by providing more efficient Generalized Least Square (GLS) estimators with a closed-form limiting distribution allowing for a more consistent (mis)pricing inference. The IPCA model...

The Elite Quality Index for 2022 (EQx2022) is the third annual publication of the internationally comparative ranking of countries on ‘elite quality’. Its aim is to provide a unique dataset for academic research, original insight on the human and economic development trajectories of nations...

Landslides are a major cause for losses and damages in railways and roadways which cross hilly regions. Some landslides may cause traffic interruption for several days, leading to severe prejudice to cargo flow in busy transportation systems, until an emergency correction can be built. Landslide...

We model a situation where a set of agents must rank themselves based on their opinions. Each agent submits a message and a function determines the social ranking. We are interested in impartial social ranking functions, that is, those where the message of an agent can not change any social...

In e-commerce, product ranking and display affect customer choices and sales as items placed in top positions receive significantly more clicks than items placed at the bottom. For retailers who sell items from the inventory they have purchased and owned, product ranking has a profound impact on...

We update citation-based rankings of economics journals to study the relative ranking of new society journals. We employ two ranking methods: a standard iterative eigenfactor methodology adjusted for reference intensity and a novel top-5 citation alternative. We find that the American Economic...

We explore how within classroom ordinal height or income rank of elementary school students affect their future academic performance. Using a Korean panel dataset covering multiple classrooms of each school in the data, we exploit the feature that two students with identical height or family...

I study the effects of congressional seniority ranks on corporate outcomes in the U.S. I show that firms located in districts of lower-ranked legislators exhibit weaker sales to government, corporate downsizing, and lower valuations. These firms are also more exposed to civil disorder, including...

Online platforms, marketplaces and retailers typically use ranking algorithms to determine the order in which hundreds or thousands of choices are presented to consumers. While ranking algorithms may aid consumer choice, there are concerns they may also lead to socially undesirable outcomes. In...

Various quasi-Newton methods periodically add a symmetric "correction" matrix of rank at most 2 to a matrix approximating some quantity A of interest (such as the Hessian of an objective function). In this paper we examine several ways to express a symmetric rank 2 matrix [delta] as the sum of...

Online marketplaces use ranking algorithms to determine the rank-ordering of items sold on their websites. The standard practice is to determine the optimal algorithm using A/B tests. We present a theoretical framework to characterize the Total Average Treatment Effect (TATE) of a ranking...

We introduce a new notion of ex-post efficiency for random assignment problems, namely ex-post rank efficiency that gives a maximal number of agents their favored objects. An ex-post rank efficient random assignment is a lottery over rank efficient deterministic assignments, in the sense of...

We introduce (strict) favoring upper ranks, which is an extension of favoring higher ranks for random assignments. We demonstrate that ex-post favoring ranks implies (strict) favoring upper ranks, and envy-freeness implies favoring upper ranks. Moreover, for at least four agents, no mechanism...

This paper presents the results from a national survey experiment that tests how voters evaluate alternative voting rules, like ranked choice voting (RCV). We examine data from the 2020 Collaborative Multiracial Post-Election Survey (CMPS), which allows for comparisons across racial groups. The...
