| 報告 | Guy Michaels (London School of Economics and Political Science) "Evaluating Urban Planning: Evidence from Dar es Salaam" (joint with Vernon Henderson, Francisco Líbano-Monteiro, Martina Manara, and Tanner Regan) [Paper] |
| Abstract | Urban informality, which is prevalent in Africa's rapidly growing cities, can reduce private investments, lower tax bases, and exacerbate urban disamenities. A key policy tool to address this problem is greenfield urban planning where governments purchase cheap agricultural land on the urban fringe and partition it into planned, surveyed, and titled de novo plots, which people can purchase and build houses on. Yet, there is very little systematic evidence on the effects of de novo planning choices, such as the size and configuration of residential and non-residential plots. We study the consequences of such planning decisions in Tanzania's "20,000 plot" project, which provided over 36,000 residential plots in 12 project areas on the fringes of Dar es Salaam in the early 2000s. We study this project using detailed maps, questionnaires, and satellite imagery, and we combine within-neighborhood analysis and spatial regression discontinuity designs. We find that overall, the project secured property rights and access, thus boosting land values, and attracting highly educated owners; small plots, which command higher land values and are built more intensively, are under-provided; access to main paved roads is prized; and development rates are higher where plot layout is more gridded and small plots are bunched together. But planned non-residential amenities are ignored due to low implementation rates and about half the plots are still unbuilt, suggesting that despite the project’s success, significant improvements are possible. |

| 報告 | Sitian Liu (Queen's University) "The effect of working from home on the agglomeration economies of cities: Evidence from advertised wages" (joint with Yichen Su) |
| Abstract | Using job posting wage data, we find a substantial decrease in the urban wage premium for occupations with high working-from-home (WFH) adoption following the COVID-19 pandemic. This decline is accompanied by an employment shift away from large employment centers. Through the lens of a stylized model, our empirical findings suggest that WFH adoption weakens the agglomeration economies of cities. A decomposition exercise reveals that the urban wage premium drop is partly driven by reduced wage returns for interpersonal skills in large cities, suggesting that the weakening of the agglomeration effect stems partially from reduced interactive activities. |

| 報告 | Nano Barahona (University of California Berkeley) "The Effects of Online Education on Market Structure and Students' Outcomes" |
| Abstract | We study the impact of a rapid expansion of the online for-profit tertiary education sector in Brazil over the past 15 years on market structure and students' outcomes. We leverage variation across regions with differential exposure to potential entrants induced by a regulatory reform that decreased the cost of opening online degrees in specific fields of study. We find that online degrees' entry to local markets expands access to tertiary education but also diverts students from alternative in-person degrees. Increased competition decreases in-person degrees' market power and deters future entry. We develop and estimate an entry and exit model where institutions choose what degrees to offer and what tuition fees to charge. We use the model to quantify the effects of the rapid expansion in online education supply on students' educational choices and outcomes. We find that in the absence of online education, students' educational value-added would have been 5\% larger. We find that policies targeting only older cohorts to attend online can keep young students at in-person degrees, reducing schools' exit and increasing the potential gains in value-added. |

| 報告 | Mitsuru Igami (伊神 満) (Yale University, Yale Department of Economics) "Welfare Gains from LCD Innovations, 2001–2011" with Shoki Kusaka, Jeff Qiu, Tuyetanh L. Tran |
| Abstract | We assess the welfare impact of new technologies by using detailed data from theglobal industry of liquid crystal display (LCD) panels. We focus on measuring bothproductivity growth via process innovation and consumer benefits from new products.We find process innovation accounted for most of the welfare gains in the computersegment, whereas product innovation played a major role in the TV segment. Wefurther decompose process innovation into vintage capital and learning by doing, andproduct innovation into larger products and other new varieties. We then conduct aseries of benefit-cost analyses to quantify the social and private returns on technologicalinvestments. Results suggest social returns were large, but most firms’ private returnswere small or negative; competitive pressure forced them to invest nevertheless. |

| 報告 | Thomas Triebs (Loughborough University) Language as a Strategic Choice—Drawing Global Research Talent by Switching to English [Paper; an older version is available on SSRN] |
| Abstract | We show, using a difference-in-difference identification, that introducing English as the official language of instruction in a degree program increases the average journal impact factor (JIF) of new international faculty hires in Dutch and Belgian universities by 12-20%. These results are robust to a battery of controls including university and time fixed effects as well as university specific time trends. We argue that switching to English reduces labor mobility barriers, allowing universities in non-English speaking countries to recruit from the global talent pool. |

| 報告 | Joshua Graff Zivin (University of California San Diego) "Disparties in Pollution Capitalization Rates: the Role of Direct and Systemic Discrimination" with Gregor Singer [Paper] |
| Abstract | We examine how exogenous changes in exposure to air pollution over the past two decades have altered the disparities in home values between Black and White homeowners. We find that air quality capitalization rates are significantly lower for Black homeowners. In fact, they are so much lower that, despite secular reductions in the Black-White pollution exposure gap, disparities in housing values have increased during this period. An exploration of mechanisms suggests that roughly one-quarter of this difference is the result of direct discrimination while the remaining three-quarters can be attributed to systemic discrimination through differential access to complementary amenities. |

| 報告 | Carlo Cambini (Politecnico di Torino, The Department of MANAGEMENT AND PRODUCTION ENGINEERING (DIGEP)) "Broadband and Innovation", by C. Cambini (Politecnico di Torino), P. Murro (LUISS, Rome), L. Sabatino (Politecnico di Torino), F. Schivardi (LUISS, Rome) e F. Sobbrio (Univ. Tor Vergata, Rome) |
| Abstract | "How advanced digital technologies affect firm’s incentives to innovate? This paper investigates the causal impact of broadband Internet on innovation using data from Italy. Thanks to web-scraped data from the European Patent Office, we identify patents with Italian inventors and allocate them across Italian municipalities based on inventors’ address. Our identification strategy exploits the staggered roll-out of DSL-based broadband connections starting from 2005, as well as the diffusion of the most recent fiber-based ultra-broadband connections started in 2015. Our results point to an increase in innovation from broadband Internet, as measured by the number of new patents, both in the first and second wave of broadband deployment." |

| 報告 | Asad Islam (Monash University) "Forced Displacement, Mental Health, and Child Development: Evidence from the Rohingya Refugees" Asad Islam, Tanvir Ahmed Mozumder, Tabassum Rahman, Tanvir Shatil, Abu Siddique [Paper] |
| Abstract | Forced displacement is a major driver of mental disorders among refugees worldwide. Poor mental health of adult refugees, particularly mothers, is also considered a risk factor for the psychological well-being and development of their children. In this study, we experimentally examine the extent to which a multifaceted psychosocial program improves the mental health of refugee mothers, and facilitates growth and development among children under the age of two. In partnership with BRAC, we ran a cluster randomized controlled trial on 3,500 Rohingya mother-child dyads in refugee camps in Bangladesh. Participants were given weekly psychosocial support for 44 weeks through peer volunteers, which includes psychoeducation and parenting support for mothers and play activities for both mothers and children. The intervention was largely successful and led to: (i) reductions in the psychological trauma and depression severity of mothers and children, (ii) improvements in communication, gross-motor, and problem-solving skills of children, and (iii) reductions in stunting and severe stunting. The intervention cost about $1 per dyad per week and is currently being scaled up in refugee camps in Bangladesh, where about seventeen thousand mother-child pairs now benefit from it. |

| 報告 | Gabriella Conti (University College London) "The Menopause “PENALTY”" Gabriella Conti, Rita Ginja, Petra Persson, Barton Willage [Paper] |
| Abstract | Menopause is a major biological shock to women, marking the end of their reproductive years. Despite its relevance, scant research has studied how menopause impacts social dynamics, labor market outcomes, or health care demand. Using high-quality linked national register administrative data from Norway and Sweden, combined with a stacked difference in-differences design, we estimate the effect of menopause diagnosis on employment and earnings, reliance on social safety net programs, and demand for medical care. We find that menopause affects a broad swath of women's lives, ranging from a temporary increase in visits to doctors, to a persistent decline in full-time employment and earnings, and an increased receipt of social transfers. The earnings losses amount to 20% relative to the pre-menopause levels. Our results suggest that policies aimed at supporting women who suffer more serious symptoms around the menopausal transition may have wide-ranging benefits. |

| 報告 | Kwok Hao Lee (National University of Singapore) "Public Housing at Scale" an old version of the paper: [Paper] |
| Abstract | We consider the design of a large-scale public housing program where consumers face dynamic tradeoffs over apartments rationed via lotteries and prices. We show, theoretically and empirically, that changing rules complements increasing supply. First, we present a motivating example in which supplying more housing leads households to strategically delay their applications. By waiting for “better” developments arriving tomorrow, households forgo mediocre developments available today, resulting in more vacancies. Turning to the data from the mechanism, we formulate a dynamic choice model over housing lotteries and estimate it. Under the existing mechanism, we find that increasing supply fails to lower wait times. However, when a strategyproof mechanism is implemented, vacancies and wait times fall, but prices on the secondary market rise. Under this new mechanism, building more apartments lowers wait times and reduces the upward pricing pressure on the secondary market. |
