Understanding the impact of the COVID-19 pandemic on education requires a solid grasp of the impact of student autonomy on learning. In this paper, we estimate the effect of an increased autonomy policy for higher-performing students on short- and longer-term school outcomes. We exploit an institutional setting with high demand for autonomy in randomly formed classrooms. Identification comes from a natural experiment that allowed higher-achieving students to miss 30 percent more classes without penalty. Using a difference-in-difference-in-differences approach, we find that allowing higher-achieving students to skip class more often improves their performance in high-stakes subjects and increases their university admission outcomes. Higher-achieving students in more academically diverse classrooms exerted more autonomy when allowed to.

ABSTRACT Evidence suggests that the significantly higher life expectancy levels witnessed over the past centuries are associated with a lower concentration of survival times, both cross-country and over time. The purpose of this work is to study the relationships that exist among models for the evolution of survival distributions, longevity measures, and concentration. We first study relationships between concentration and cohort longevity through empirical comparisons. We then propose a family of survival models that can be used to capture such trends in longevity and concentration across survival distributions.

ABSTRACT During the demographic transition that in Europe tended to take place from the early 19th to the end of the 20th century, the population in European countries and its overseas offshoots increased by a factor of five or less, which is low compared to the increase now taking place in most other regions of the world. This study provides simulations showing what global and regional population sizes would be if the rest of the world experienced similar population growth patterns as were observed in Europe. European culture distinguished itself through choices that led to the European marriage pattern, characterized by late marriage, significant shares not marrying, low levels of extramarital childbearing, and comparatively low fertility. One important consequence was the relatively low population growth characterizing the cultures, religions, and ethno-linguistic groups where the European marriage pattern was dominant.

How do tax incentives affect firms’ investment? Using confidential UK corporation tax returns, we provide new evidence on the effects of incentives in the form of depreciation allowances. We exploit a 2004 exogenous change in the qualifying thresholds for the first-year depreciation allowances (FYAs) and conduct a difference-in-difference analysis. Results suggest that the investment rate increased between 2.1 and 2.6 percentage points when firms became qualified for FYAs, relative to firms that never qualified. This implies an increase in investment rate of 11 percent at the mean. We exploit exogenous variation in the timing of tax payments to show that this large effect is not due to an increase in available cash and hence, this is primarily a cost of capital effect. Firms respond rather quickly to FYAs, within 12 to 18 months. Firms also bunch just below notches in the cost of capital created by the qualifying thresholds, suggesting salience of the FYAs. Such behaviour does not drive our main results.

ABSTRACT This paper examines how companies’ capital structure is affected by the corporate income tax system. Our analysis employs confidential company-level corporation tax return data in the UK. Our main identification strategy is based on variation in companies␣ marginal tax rates due to the existence of kinks in the corporate tax rate schedule. Using a dynamic adjustment model of capital structure, we find a positive and substantial long-run tax effect on companies' financial leverage. We show that there are considerable discrepancies between estimates of taxable profits reported in tax return data and in financial statements and that the estimated tax effect on capital structure using financial statements is likely to be biased downward. We find that companies adjust their capital structures gradually in response to changes in the marginal tax rate. Moreover, we find that the external leverage of domestic stand-alone companies and of multinational companies responds strongly to corporate tax incentives

We define as populist a party that champions short-term protection policies without regard for their long-term costs. First, we study the demand for populism: we analyze the drivers of the populist vote using individual level data from multiple waves of surveys in Europe. Individual voting preferences are in uenced directly by different measures of economic insecurity and by the decline in trust in traditional parties. However, economic shocks that undermine voters' security and trust in parties also discourage voter turnout, thus mitigating the estimated demand of populism when ignoring this turnout selection. Economic insecurity affects intentions to vote for populist parties and turnout incentives also indirectly because it causes trust in parties to fall. Second, we study the supply side: we find that populist parties are more likely to appear when the drivers of demand for populism accumulate, and more so in countries with weak checks and balances and with higher political fragmentation. The non-populist parties' policy response is to reduce the distance of their platform from that of new populist entrants, thereby magnifying the aggregate supply of populist policies.

ABSTRACT This research note presents and compares some first findings obtained by the project EINITE-Economic Inequality across Italy and Europe, 1300-1800. The main aim of the project is to investigate long-term trends in economic inequality in Italy and in Europe. Here we compare previously published data for Piedmont with some early findings for Lombardy and Veneto, in order to provide a broad picture of northern Italian inequality. The period we cover is particularly long (13th–early 19th centuries) for Piedmont, while for Lombardy and Veneto a somewhat shorter period is considered (15th–18th centuries). We provide an in-depth analysis of the archival sources usable to study long-term changes in economic inequality in northern Italy, and we provide some key measures of inequality over time (Gini indexes, top percentiles). We find evidence of a tendency for Italian inequality to increase almost everywhere and almost continuously over time, since about 1400 or 1450, confirming what has been suggested by previous studies that focused on Piedmont and Tuscany.

Public procurement outcomes depend on the ability of the procuring agency to select well-performing suppliers. Should public administrations be granted more or less discretion in their decision making? Using Italian data on municipal public works tendered in the period 2009-2013, we study how a reform extending the scope of bureaucrat discretion affects supplier selection. We find that the share of contracts awarded to politically connected firms increases while the (ex-ante) labor productivity of the winning firm decreases, thus suggesting a potential misallocation of the public funds. These effects are concentrated among lower quality procuring agencies.

This paper presents measures of differential mortality in Italy by educational level. The results refer to the year 2001 because the census is the only source providing data about population by level of education; as to deaths the data are provided by death certificates. As often happens, in order to compute differential mortality using these period frequencies it was necessary to confront problems both in the use of unlinked records and in relation to limitations in statistical documents; that is why we classified the population in only two groups: one with a low level of education and the other with a high level. We used a logit relational method to build life tables according to the levels of education. Particular attention was given to expectation of life at the ages from 35 to 65. At 35 years of age the expectation of life for a person with a low level of education is about 7.5 years less than for a person of a higher level in case of a male, and 6.5 years less in case of a female. The tendency continues, and at the age of 65 the expectation for those with a lower level is one quarter less in case of males and one fifth less in case of females. We found that a linear relationship exists between life expectancy and standardized rates among the Italian provinces; the same relation is also true for the analogous indicators of differential mortality by educational level.

We investigate the role of individual labor income as a moderator of parental subjective well-being trajectories before and after the first childbirth in Germany, a very low fertility country. Analyzing German Socioeconomic Panel Survey data, we found that income matters negatively for parental subjective well-being after childbirth, though with important differences by education and gender. In particular, among better educated parents, the richer see the arrival of a child more negatively. These findings contribute to the debate on the relationship between income and fertility adding information on how parents perceive the birth of a child beyond the strict financial cost of childbearing and raising. Results are discussed in terms of preferences among different groups of parents, costs of children, and work and family balance. Results are robust to potential endogeneity between income and childbirth, as well as for alternative measures of income.
