- This paper develops a maximum likelihood (ML) bunching estimator of the elasticity of taxable income (ETI). Our structural approach provides a natural framework to simultaneously account for unobserved preference heterogeneity and optimization errors and for measuring their relative importance. We characterize the conditions under which the parameters of the model are identified and show that the ML estimator performs well in terms of bias and precision. The paper also contains an empirical application using Swedish data, showing that both the ETI and the standard deviation of the optimization friction are precisely estimated, albeit relatively small.

Maximum Likelihood Bunching Estimators of the ETI
- 2021
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- We propose a maximum likelihood method to improve the bunching approach of estimating the elasticity of taxable income (ETI), and derive estimators for several model settings such as bunching with optimization frictions, notches, and heterogeneity in the ETI. Modelling optimization frictions explicitly, our estimators fit the data of several published studies very well. In the presence of a notch, the results can differ substantially from those obtained using the polynomial approach. If there is heterogeneity in the ETI, the elasticity among those who bunch exceeds the average elasticity in the population.

Tidskriftsartikel (refereegranskat)abstract
- The elasticity of taxable income (ETI) is a central statistic for tax policy design. One purpose of the present paper is to use Monte Carlo simulation techniques to assess the bias and precision of the prevalent estimators in the literature, the IV-regression estimator and the bunching estimator. Thereby, we aim to provide arguments in favor of, or against, using these methods. Another is to suggest indirect inference estimation to improve the quality of the measurement of the ETI. While IV-regression estimators perform well in terms of bias under certain conditions, they are more variable than bunching estimators. We also find that bunching estimators can be biased downward. The estimators based on indirect inference principles are practically unbiased and more precise than the other estimators.

Empirical essays on military service and the labour market
- 2023
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis consists of an introductory part and four self-contained papers that study empirical questions related to military service and the labour market.Paper [I] studies the relationship between civilian labour market conditions and the number of people who volunteer for military service in Sweden. I use panel data on Swedish counties for the years 2011 through 2015 and study the effect of civilian unemployment on the rate of applications from individuals aged 18 to 25 to initiate basic military training. The results indicate a positive and statistically significant relationship between the unemployment rate and the application rate, and suggest that the civilian labour market environment can give rise to non-trivial fluctuations in the supply of volunteers to the Swedish military.Paper [II] studies how local labour market conditions influence the quality composition of those who volunteer for military service in Sweden. I estimate a fixed-effects regression model on a panel data set containing cognitive ability test scores for those who applied for military basic training across Swedish municipalities during the period 2010 to 2016. The main finding is that if civilian employment rates at the local level go up, the average test score of those who volunteer for military service goes down. The results suggest that, due to the way in which different types of individuals select themselves into the military, the negative impact of a strong civilian economy on recruitment volumes is reinforced by a deterioration in recruit quality.Paper [III] studies the effect of peacekeeping on post-deployment earnings for military veterans. Using Swedish administrative data, we follow a sample of more than 11,000 veterans who were deployed for the first time during the period 1993-2010 for up to nine years after returning home. To deal with selection bias, we use difference-in-differences propensity score matching based on a rich set of covariates, including measures of individual ability, health and pre-deployment labour market attachment. We find that, overall, veterans’ post-deployment earnings are largely unaffected by their service. Even though Swedish veterans in the studied period tend to outperform their birth-cohort peers who did not serve, we show that this advantage in earnings disappears once we adjust for non-random selection into service. Paper [IV] studies the relationship between military deployment to Bosnia in the 1990s and adverse outcomes on the labour market. The analysis is based on longitudinal administrative data for a sample of 2275 young Swedish veterans who served as peacekeepers in Bosnia at some point during the years 1993–1999. I follow these veterans for up to 20 years after deployment. Using propensity score matching based on a rich set of covariates, I estimate the effects of deployment on three broad measures of labour market marginalisation: long-term unemployment, work disability, and social-welfare assistance. I find no indication of long-term labour market marginalisation of the veterans. Even though the veterans experienced an increase in the risk of unemployment in the years immediately following return from service, in the long run their attachment to the labour market is not affected negatively by their service.

Essays on military labour supply in the era of voluntary recruitment
- 2020
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis consists of an introductory part and two self-contained chapters related to the supply of volunteers to the Swedish Armed Forces.Chapter [I] represents the first effort to explore the relationship between civilian labour market conditions and the supply of labour to the military in the all-volunteer environment that Sweden entered after the abolishment of the peacetime draft in 2010. The effect of civilian unemployment on the rate of applications from individuals aged 18 to 25 to initiate basic military training is investigated using panel data on Swedish counties for the years 2011 through 2015. A linear fixed-effects model is estimated to investigate the relationship, while controlling for a range of socio-demographic covariates and unobserved heterogeneity on the regional level, as well as aggregate trends on the national level. The results indicate a positive and statistically significant relationship between the unemployment rate and the application rate. The results are robust to non-linear form specifications, as well as allowing the civilian unemployment rate to be endogenous. As such, the results suggest that the civilian labour market environment in Sweden can give rise to non-trivial fluctuations in the supply of applications to initiate basic military training within the Swedish Armed Forces.Chapter [II] studies how local labour market conditions influence the quality composition of those who volunteer for military service in Sweden. A fixed-effects regression model is estimated on a panel data set containing IQ scores for those who applied for military basic training across Swedish municipalities during the period 2010 to 2016. The main finding is that low civilian employment rates at the local level tend to increase the mean IQ score of those who volunteer for military service, whereas the opposite is true if employment rates in the civilian labour market move in a more favourable direction. As such, the results suggest that the negative impact of a strong civilian economy on recruitment volumes is reinforced by a deterioration in recruit quality.

Essays on labor supply, pension policy, and inequality
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Paper [I] analyzes the dynamic properties of life-cycle earnings in Sweden using microdata. We study the evolution of permanent and transitory earnings inequality over the period 2002--2015. Our data comes from administrative records gathered in the ASTRID database. We find that some features of the data do not match the predictions of the heterogeneous or restricted income profile models commonly applied in the earning dynamics literature. Instead, we estimate an alternative permanent-transitory (PT) error components model. Analyzing the covariance structure of both male and female earnings, controlling for educational background, we find that the upward trend in permanent earnings inequality observed in Sweden during the 1990s does not continue in the 2000s, and the financial crisis of 2008 did not have any major impact on the variability of earnings. We further simulate the accumulation of income pension entitlements and find that variations in pension entitlements are smaller among college-educated workers. Paper [II] studies the life-cycle effects of favorable marginal tax treatment on older workers' optimal life-cycle labor supply, retirement timing, and savings. I develop a structural model in continuous time where the life cycle of a representative agent is divided into three distinct phases: pre-treatment, post-treatment, and retirement. Solutions for consumption and savings, labor supply and leisure, and retirement timing are then obtained by solving the model as a salvage value problem. I then calibrate the model to Swedish earnings data and find that the increased extensive margin labor supply is partially offset by a reduction in hours worked during the pre-treatment period. The total effect, however, is an increase in life-cycle labor supply and consumption. \\Paper [III] studies the implications of the structure of public pension programs for the trade-offs determining economic behavior over the life cycle. The economy is modeled as a continuous-time overlapping generations model with endogenous labor supply, savings, and human capital formation. Individuals differ in ability and are free to choose how much to work at each period in time and when to enter and exit the labor market. Numerical simulations provide qualitative insights that a redistributive pension system introduces opposite effects on the incentives for retirement for high- and low-skilled individuals, which leads to increased earnings inequality. This effect can, in turn, dominate reduced pension inequality such that lifetime and population-wide income inequality increase. Ultimately, the equity–efficiency trade-off is found to be difficult to characterize. \noindent \\Paper [IV] explores the effects of pension illiteracy on aggregate labor supply and the redistributive performance of public pension systems. I consider an OLG model in continuous time populated with individuals who differ in labor productivity and pension literacy. Agents suffering from pension illiteracy fail to fully account for the structure of the pension system when planning their economic behavior over the life cycle. I find that pension illiteracy can negatively impact aggregate labor supply and increase earnings inequality and lifetime income inequality. This suggests that pension illiteracy may limit the efficiency gains of an increased correlation between individual contributions and benefits, making the equity–efficiency trade-off difficult to characterize in the context of pension reforms.

Essays on earnings formation, labor market dynamics, and taxation
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Chapter [I] analyses the dynamic properties of life-cycle earnings of men and women in Sweden by fitting a model to the covariance structure of earnings. We find that the financial crisis of 2008 did not have any major impact on the variability of earnings and that the upward trend in permanent earnings inequality observed in Sweden during the 1990s does not continue in the 2000s. Using the model to simulate the accumulation of income pension entitlements, we find that college-educated workers have smaller variations in pension entitlements than workers with less education.Chapter [II] presents a life-cycle earnings dynamics model that includes endogenous employment and job change. The model is estimated on Swedish register data using indirect inference. By simulating data from this model, we study the macroeconomic consequences of transitory shocks to unemployment risk, how unemployment at different ages affects the accumulation of pension entitlements, and analyze how different factors contribute to earnings inequality. We find that transitory aggregate shocks to unemployment risk have long-lasting negative effects on employment and earnings, that becoming unemployed at age 40 has a large negative effect on pension accumulations, and that unobserved individual heterogeneity contributes substantially to the observed life-cycle earnings inequality for both men and women in Sweden.Chapter [III] presents a model of earnings dynamics that includes transitions in and out of employment and business cycle fluctuations. The model is estimated using indirect inference and a mix of Swedish register, survey and macro data. We find that the transitions from unemployment to employment are more sensitive to business cycle fluctuations than the probability of remaining employed. By simulating data from the model, we find that the business cycle has a relatively small impact on earnings inequality in Sweden and that young workers are more sensitive to business cycle fluctuations than older workers.Chapter [IV] deals with optimal nonlinear taxation of income and profits in a general equilibrium model with frictional unemployment. We find that the government can achieve redistribution of income through taxation without distorting production efficiency. This outcome is possible if the government uses two nonlinear tax instruments, taxing profits and labor income separately. The results also show that including involuntary unemployment creates an incentive to tax entrepreneurial income at lower marginal rates and labor income at higher marginal rates than otherwise.

Before political economy: debate over grain markets, dearth and pauperism in England, 1794–96

Tidskriftsartikel (refereegranskat)abstract
- During the 1790s Britain experienced a series of poor harvests which, given an expanding population and wartime disruption to the European grain trade, caused sudden and rapid increases in the domestic price of wheat. In modern discussion of Corn and Poor Laws the severity of these fluctuations has been obscured by the use of annual average grain prices, despite weekly county prices being available from 1771 as published in the London Gazette. We highlight the uncertainties of grain prices during the period 1794-96, drawing upon contemporary discussion published in the Annals of Agriculture of the problems arising from fluctuations in the price of wheat. Our purpose is to demonstrate that the tropes usually today associated with the Corn and Poor Laws – pauperism, a clash between merchant, manufacturing and landlord interests, population and impoverishment – are absent from discussion during this period. A doctrinaire “political economy” would develop in the early 1800s, but did not yet exist. Policy argument drew upon casuistic reasoning from circumstance and past experience. We also show in conclusion that Edmund Burke’s Thoughts and Details on Scarcity cannot be linked to “political economy”.

The price elasticity of electricity demand when marginal incentives are very large
- 2020
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Using unique data on Swedish households, we measure the price elas- ticity of electricity demand for households facing a mandatory non-linear distribution tariffs where households are charged based on their maximum consumption during a month, and where the marginal incentives are very large. We estimate the price elasticity using both 2SLS and bunching esti- mators, and we find that the price elasticity is smaller than what previous literature on electricity demand have found. Furthermore, we illustrate why charging households based on maxi- mum consumption during a month leads to weak incentives in the end of the month, and discuss alternative tariff designs.

We estimate the price elasticity using both 2SLS and bunching estimators, and we find that the price elasticity is smaller than what many previous studies on electricity demand have found.We show that the 2SLS estimates are not robust to changes to the set of controls or to the sample definition, while the bunching estimates suggest that the price elasticity of electricity demand is small in response to the large marginal incentives.Furthermore, we illustrate why charging households based on maximum consumption during a month leads to weak incentives in the end of the month, and discuss alternative tariff designs.
