Excise taxes and commodity promotion bayesian retrieval of the optimum

This article shows how the solution to the promotion problem—the problem of locating the optimal level of advertising in a downstream market—can be derived simply, empirically, and robustly through the application of some simple calculus and Bayesian econometrics. We derive the complete distribution of the level of promotion that maximizes producer surplus and generate recommendations about patterns as well as levels of expenditure that increase net returns. The theory and methods are applied to quarterly series (1978:2S1988:4) on red meats promotion by the Australian Meat and Live-Stock Corporation. A slightly different pattern of expenditure would have profited lamb producers

Taxes, corruption, and entry

Tax policies and corruption are important institutional considerations which can shape entrepreneurship. We investigate how tax rates, and the interaction between corruption and tax rates, influence variations in entry across a panel of 72 countries in the period 2005–2011. We use a series of panel estimations as well as several robustness checks to test these effects, using relevant controls for economic development, the size of the state, and other regulatory and tax policy measures. We find that higher tax rates consistently discourage entry. Further, we find that although the direct influence of corruption on entry is also consistently negative, the interaction influence of corruption and tax rate is positive. This indicates that corruption can offset the negative influence of high taxes on entry. We discuss the implications of our findings for policymakers and future research.

The distributional and nutritional impacts and mitigation potential of emission-based food taxes in the UK

Agriculture and food production are responsible for a substantial proportion of greenhouse gas emissions. An emission based food tax has been proposed as one option to reduce food related emissions. This study introduces a method to measure the impacts of emission based food taxes at a household level which involves the use of data augmentation to account for the fact that the data record purchases and not consumption. The method is applied to determine the distributional and nutritional impacts of an emission based food tax across socio-economic classes in the UK. We find that a tax of £2.841/tCO2e on all foods would reduce food related emissions by 6.3% and a tax on foods with above average levels of emissions would reduce emissions by 4.3%. The tax burden falls disproportionately on households in the lowest socio-economic class because they tend to spend a larger proportion of their food expenditure on emission intensive foods and because they buy cheaper products and therefore experience relatively larger price increases.

Financial disruption as a cost of sovereign default

This dissertation analyses quantitatively the costs of sovereign default for the economy, in a model where banks with long positions in government debt play a central role in the financial intermediation for private sector's investments and face financial frictions that limit their leverage ability. Calibration tries to resemble some features of the Eurozone, where discussions about bailout schemes and default risk have been central issues. Results show that the model captures one important cost of default pointed out by empirical and theoretical literature on debt crises, namely the fall in investment that follows haircut episodes, what can be explained by a worsening in banks' balance sheet conditions that limits credit for the private sector and raises their funding costs. The cost in terms of output decrease is though not significant enough to justify the existence of debt markets and the government incentives for debt repayment. Assuming that the government is able to alleviate its constrained budget by imposing a restructuring on debt repayment profile that allows it to cut taxes, our model generates an important difference for output path comparing lump-sum taxes and distortionary. For our calibration, quantitative results show that in terms of output and utility, it is possible that the effect on the labour supply response generated by tax cuts dominates investment drop caused by credit crunch on financial markets. We however abstract from default costs associated to the breaking of existing contracts, external sanctions and risk spillovers between countries, that might also be relevant in addition to financial disruption effects. Besides, there exist considerable trade-offs for short and long run path of economic variables related to government and banks' behaviour.

The optimality of the Friedman rule when some distorting taxes are exogenous

This paper investigates the optimality of the Friedman rule in a two-sector small open economy. That policy prescription is found to be a necessary condition for Pareto efficiency. If a planner can select all conceivable distorting taxes, then, for some initial values of public debt, money balances and foreign assets, it is possible to decentralize a Pareto efficient allocation. If the planner can select only some of these tax rates, then second-best policies may also satisfy the Friedman rule. However, this last result depends on the set of tax instruments the planner can choose from.

Sugar-Sweetened Beverage Taxes in Brazil

Objectives. We investigated whether taxing sugar-sweetened beverages (SSBs) would improve the diets of households in Brazil. Methods. We used household food consumption data that the Brazilian Institute of Geography and Statistics collected in 2002-2003 from a nationally representative sample of 48470 Brazilian households. The consumption of SSBs is expressed as the total SSB calories consumed and as the SSB percentage of the total calories purchased. We investigated price elasticity with regression models, controlling for demographic variables, income, and prices of all other foods and drinks. Results. Increases in the price of SSBs led to reductions in consumption. A 1.00% increase in the price of SSBs led to a 0.85% reduction of SSB calories consumed (1.03% reduction for the poor and 0.63% for the nonpoor). Increased income had a positive effect on SSB consumption, but the effect was less than half the size of the price elasticity (0.41% increase in SSB calories consumed for every 1.00% increase in income). Conclusions. High SSB price elasticity in Brazil indicates that a tax on purchased weight or volume would lead to reductions in SSB consumption.

Do Taxes Matter in the CAPM?

The traditional literature on the CAPM assumes that investor's tax payments simply vanish from the model. This assumption is not at all consistent with the actual behavior of the Treasury. The theory of general equilibrium states that an interest rate rf = 0 will not affect prices if taxes are introduced. We show that this result can be extended to the CAPM if the tax payments are redistributed among investors.
