Essays in International Trade : Measurement, Product Quality, Input-Output Modelling and Tax Evasion
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis consists of four independent essays that deal with several measurement aspects within the field of international trade. The measurement problems addressed are related to measuring the human capital content of trade in exports relative to imports or measuring tax evasionEssay 1, The Human Capital Content of Trade and its Measurement. Evidence from Swedish Data, deals with various measurement problems related to calculations of the human capital content of trade in exports relative to imports. This builds on the Heckscher-Ohlin-Vanek extension to the Heckscher-Ohlin trade theory.Essay 2, Product Quality Adjustment and the Human Capital Content of Trade. A New Computational Framework, builds on the same theoretical background, but introduces a quality-adjustment in the calculations of the human capital content of trade in exports relative to imports, which builds on the idea underlying vertical intra-industry trade (VIIT). Quality adjustment is performed, first, by assuming that a product sold at a higher price has a higher quality than the same product sold at a lower price and, second, by assuming that a highquality product implies a higher content of skilled labour than a low-quality product.Essay 3, Estimation of commodity-by-commodity input–output matrices, focuses on a new method in constructing symmetric input-output tables (SIOTs), which has been termed the Bohlin and Widell model, using data contained within supply- and use-tables (SUTs). One key contribution is that it makes it possible to estimate SIOTs in cases when the underlying SUTs are rectangular. The method also addresses the problem of negative coefficients, a long-standing issue encountered in the derivation of SIOTs.Essay 4, Tax evasion in Kenya and Tanzania: Evidence from missing imports, focuses on estimating the amount of tax evasion in trade between Kenya and Tanzania. The study is empirically focused, and the measurement errors in reported trade flows between both countries are correlated with tax rates, to determine whether the measurement error increases with the tax rate.

Taxation of intermediate goods : a CGE analysis
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This dissertation is concerned with tax rates for the use of commodities in general, and energy in particular. Computable General Equilibrium (CGE) models are used to analyze the normative question of whether the tax rate for intermediate use by firms should be the same as the tax rate for final consumption by households. To answer this question, a distinction needs to be made between fiscal taxes for the purpose of raising revenue for the government, and Pigovian taxes for the purpose of changing behaviour. Concerning fiscal taxes, firms should not pay taxes on their use of inputs if the tax rates in final consumption are at their optimal level. If the tax rate for households is above the optimal level, intermediate use in firms should be taxed in order to increase the price of other commodities and reduce the distortion of relative prices. Essay 1 ascertains what factors determine the optimal relation between the tax rate for final consumption by households and intermediate use by firms. Essay 2 analyses Swedish energy taxes from the perspective of reducing global emission of CO2. It is found that the welfare maximizing tax rates are equal for households and firms not participating in emission trading, while firms that participate in emission trading should have a zero tax rate. Essays 3 and 4 deal with methodological issues. Essay 3 derives a new method for estimation of symmetric input-output tables from supply and use tables. This method solves the problem of negative coefficients, makes it possible to use both the industry and commodity technology assumptions simultaneously and enables the commodity technology assumption to be used even when the number of commodities is larger than the number of industries. Essay 4 describes the model used in the first two essays. The price structure developed here makes it possible to take into account price differences between different purchasers other than differences in tax rates. This essay also makes a comparison between the Swedish implementation of this model and other Swedish CGE-models used to analyse climate policy and energy taxation.

Organizing for efficiency : Essays on merger policies, independence of authorities, and technology diffusion
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Institutions are fundamentally sets of rules in a society that help create stability. Organizations are groups of people who may share the same goal. Changes in organizations and institutions will have large effects on the performance of economies. This thesis explores empirical aspects concerning two elements of institutional and organizational design: economic regulations and independent regulatory authorities (IRAs).Essay 1 studies the impact of the 2004 EU merger policy reform on how mergers are reviewed by the European Commission. The EU policy appears to have softened after the reform for unilateral mergers and this may suggest an improvement of merger policy efficiency.Essay 2 compares the merger enforcements in the EU and the US. Our approach is to decompose the differences into policy effects and casemix effects. The EU policy has significantly changed after its 2004 reform. Overall, the results show a convergence between the two policies for dominance mergers after the EU policy reform.Essay 3 constructs an independence index for 109 European IRAs in six different sectors: competition, energy, financial markets, pharmaceuticals, food safety, and telecom. Factor analysis suggests that the heads of the agencies are mostly constrained by four factors: collegial bodies, the judicial system, politics and scope of tasks, and resources.Essay 4 explores a correlation between independence of regulatory authorities and corruption. We find that the authorities in corrupt countries to a large extent rely on collegial bodies but are less tightly controlled by the judicial system, compared with those in “clean” countries.Essay 5 studies the impact of regulation on broadband diffusion speed. The results imply that a strict local loop unbundling policy appears to slow the diffusion speed of fixed broadband. In contrast, a procompetition policy that aims to promote entry has a significant positive impact on the diffusion speed of mobile broadband.

Welfare Effects of Transport Policies : an analysis of congestion pricing and infrastructure investments
- 2011
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Interactions between the transport market and other distorted markets, such as the labor market, can have a large impact on the overall welfare effect of a road pricing policy or a congestion charge. Many road pricing studies therefore try to incorporate effects from other distorted markets in the analysis. A difficulty when assessing the welfare effect of a future transport policy is also that many factors and parameters needed for the analysis is uncertain. This thesis contains three papers all studying different methodological approaches to analyzing the welfare effects of transport policies. The first two papers analyze the welfare effect of congestion pricing in distorted economies. The main contribution of the first paper is to analyze how the welfare effect of a congestion charge in a distorted economy depends on what assumptions we make regarding the tax system in the initial no-toll situation. A critical assumption in many cost-benefit analyses of congestion charges is that the whole population has a single value of time. The second paper studies the effect of a congestion charge in a population of commuters with a continuously distributed value of time. The main contribution of the paper, compared to previous literature, is that it studies the welfare effect and distributional impact of a congestion charge in a population with endogenous labor supply and heterogeneous value of time where mode-choice self-selection plays an important role. The third paper studies the climate benefit of an investment in high speed rail by calculating the magnitude of annual traffic emission reduction required to compensate for the annualized embedded emissions from the construction of the line. To account for uncertainties in underlying assumptions, a Monte Carlo simulation framework is used in the analysis. The paper finds that to be able to balance the annualized emissions from the construction, traffic volumes of more than 10 million annual one-way trips are usually required, and most of the traffic diverted from other transport modes must come from aviation.

Multi-unit common value auctions : theory and experiments
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Research on auctions that involve more than one identical item for sale was,almost non-existing in the 90’s, but has since then been getting increasing attention. External incentives for this research have come from the US spectrum, sales, the European 3G mobile-phone auctions, and Internet auctions. The policy relevance and the huge amount of money involved in many of them have helped the theory and experimental research advance. But in auctions where values are equal across bidders, common value auctions, that is, when the value depends on some outside parameter, equal to all bidders, the research is still embryonic.This thesis contributes to the topic with three studies. The first uses a Bayesian game to model a simple multi-unit common value auction, the task being to compare equilibrium strategies and the seller’s revenue from three auction formats; the discriminatory, the uniform and the Vickrey auction. The second study conducts an economic laboratory experiment on basis of the first study. The third study comprises an experiment on the multi-unit common value uniform auction and compares the dynamic and the static environments of this format.The most salient result in both experiments is that subjects overbid. They are victims of the winner’s curse and bid above the expected value, thus earning a negative profit. There is some learning, but most bidders continue to earn a negative profit also in later rounds. The competitive effect when participating in an auction seems to be stronger than the rationality concerns. In the first experiment, subjects in the Vickrey auction do somewhat better in small groups than subjects in the other auction types and, in the second experiment, subjects in the dynamic auction format perform much better than subjects in the static auction format; but still, they overbid.Due to this overbidding, the theoretical (but not the behavioral) prediction that the dynamic auction should render more revenue than the static fails inthe second experiment. Nonetheless, the higher revenue of the static auction comes at a cost; half of the auctions yield negative profits to the bidders, and the winner’s curse is more severely widespread in this format. Besides, only a minority of the bidders use the equilibrium bidding strategy.The bottom line is that the choice between the open and sealed-bid formats may be more important than the choice of price mechanism, especially in common value settings.
