Lessons in Harmony: What Experience in the Atlantic Provinces Shows About the Benefits of a Harmonized Sales Tax

Provincial retail sales taxes are remarkably high on business inputs, including purchases of capital goods that spur growth in productivity and employment. Evidence from Eastern provinces with a Harmonized Sales Tax (HST) suggests that harmonizing provincial sales taxes with the federal GST would eliminate most of this distortion, without leading to an increase in consumer prices.tax reform, retail sales taxes

Limited liability and the development of capital markets

We study the consequences of the introduction of widespread limited liability for corporations. In the traditional view, limited liability reduces transactions costs and enhances investment incentives for individuals and firms. But this view does not explain several important stylized facts of the British experience, including the slow rate of adoption of limited liability by firms in the years following legal reforms. We construct an alternative model that accounts for this and other features of the nineteenth century British experience. In the model, project risk is private information, and a firm’s decision to adopt limited liability may be interpreted in equilibrium as a signal the firm is more likely to default. Hence less risky firms may choose unlimited liability or forego investments entirely. We show the choice of liability rule can lead to "development traps," in which profitable investments are not undertaken, through its effect on equilibrium beliefs of uninformed investors in the economy.Limited liability ; Capital market

Tax Credits and the Use of Medical Care

Several recent proposals have advocated using the income tax system to collect user fees to help fund the health care system. While there is a considerable amount of research investigating both how individuals respond to tax incentives for employer provided health insurance and on the effects of user fees payable at the point of service on the use of health care services, there is limited evidence on how individuals respond to tax incentives when these are not realized until taxes are paid. This paper uses existing exemptions in the Canadian tax code that allow individuals to deduct the cost of health care or health insurance from their taxable income in order to identify the tax price elasticity of demand for health care when price changes are realized at the end of the tax year. Our results suggest that despite not realizing the tax benefit at the time of purchase, individuals are quite responsive to changes in the tax price of health care. Our elasticity estimates for a wide range of health care products are well within the range of traditional price elasticity estimates, including in particular our estimates for prescription drugs. We also find some evidence that suggests individuals trade off risk sharing through traditional insurance companies with risk sharing through the tax code. That is, as the tax price of health care decreases, individuals spend more on health care, but spend less on health insurance.

Income Shifting, Investment, and Tax Competition: Theory and Evidence from Provincial Taxation in Canada

We study corporate income tax competition when firms operating in multiple jurisdictions can shift income using financial planning strategies. Several such strategies, particularly intra-corporate lending, appear to be actively pursued by companies to reduce subnational corporate taxes in Canada. A simple theoretical model shows how interjurisdictional tax planning can give rise to asymmetries in jurisdictions’ tax policies, with one jurisdiction becoming a “tax haven” to attract taxable income through financial transactions, while others set higher statutory rates. Further, increased competition from tax havens may paradoxically lead to tax increases by high-tax jurisdictions. Analysis of data from administrative tax records suggests income shifting has pronounced effects on provincial tax bases in Canada. According to our preferred estimate, the elasticity of taxable income with respect to tax rates for "tax shifting" firms is 4.3, compared to 1.6 for other, comparable firms.

In Praise of Tax Havens: International Tax Planning and Foreign Direct Investment

The multinationalization of corporate investment in recent years has given rise to a number of international tax avoidance schemes that may be eroding tax revenues in industrialized countries, but which may also reduce tax burdens on mobile capital and so facilitate investment. Both the welfare effects of and the optimal response to international tax planning are therefore ambiguous. Evaluating these factors in a simple general equilibrium model, we find that citizens of high-tax countries benefit from (some) tax planning. Paradoxically, if tax rates are not too high, an increase in tax planning activity causes a rise in optimal corporate tax rates, and a decline in multinational investment. Thus fears of a “race to the bottom” in corporate tax rates may be misplaced.income shifting, tax planning, foreign direct investment, tax competition, thin capitalization

Corporate Lobbying and Commitment Failure in Capital Taxation

This paper investigates the effects of lobbying by corporations when investments are irreversible and government cannot commit to tax policies. We show that industries which rely more heavily on sunk capital lobby more vigorously and are generally more successful in obtaining tax breaks. Thus lobbying can mitigate the capital levy problem. Nevertheless, these industries invest less in long-run equilibrium than more flexible ones. We then consider the effects of relaxing legal restrictions on corporate lobbying. When the deadweight costs of lobbying fall, taxes on sunk capital tend to fall, but political contributions may rise, as lobbyists compete more intensively for political favors. On balance, a ban of lobbying may therefore cause investment to rise or fall.

Regional Grants as Pork Barrel Politics

We investigate the political and economic factors influencing the allocation of regional development grants for a panel of Canadian electoral districts in the 1988-2001 period. In a strong party system such as Canada’s, models of political competition predict little role for individual legislators, as party leaders allocate resources to maximize party success. While spending is targeted toward some “swing” districts, we do also find it is higher in districts represented by members of the government party, especially those in the federal Cabinet, and those of lower seniority. We develop a model featuring bargaining over legislative and non-legislative favours that is consistent with the evidence.

Business Tax Lobbying

This paper investigates the effects of business tax lobbying in the presence of investments that are sunk or costly to adjust in the short run. We show that industries which rely more heavily on sunk capital are generally more successful in obtaining tax breaks through lobbying; this reverses the usual logic of the capital levy problem. Nevertheless, these industries invest less in long-run equilibrium than more flexible ones. We then consider the effects of relaxing legal restrictions on corporate lobbying. When politicians give more weight to lobbyists' preferences, taxes fall on average and investment rises. But investment is misallocated among industries, so that welfare may fall. Thus restrictions on business lobbyists may be desirable. Dans ce texte, nous étudions le lobbying des sociétés visant à réduire leurs impôts lorsque le capital qu'elles utilisent est irrécupérable ou coûteux à ajuster à court terme. Il est démontré que grâce au lobbying, les industries utilisant un capital relativement coûteux à ajuster obtiennent les baisses d'impôt les plus substantielles. Néanmoins, ces industries investissent moins à long terme que celles utilisant un capital plus flexible. Nous étudions également l'effet d'une libéralisation des règles encadrant le lobbying des sociétés. Lorsque les politiciens attachent plus d'importance aux préférences des lobbies, le niveau moyen de taxation diminue et l'investissement augmente. Le bien-être peut cependant diminuer à cause de la mauvaise répartition de l'investissement entre les industries. Un certain encadrement du lobbying des sociétés peut donc être désirable.Lobbying, Business taxation, Investment

The Efficiency Consequences of Local Revenue Equalization: Tax Competition and Tax Distortions

This paper shows how a popular system of federal revenue equalization grants can limit tax competition among subnational governments, correct fiscal externalities, and increase government spending. Remarkably, an equalization grant can implement efficient policy choices by regional governments, regardless of a wide variety of differences in regional tax capacity, tastes for public spending, and population. Thus, compared to other corrective devices, equalization achieves “robust” implementation. If aggregate tax bases are elastic, however, equalization leads to excessive taxation. Efficiency can be achieved by a modified formula that equalizes a fraction of local revenue deficiencies equal to the fraction of taxes that are shifted backward to factor suppliers.tax competition, intergovernmental grants

Is Targeted Tax Competition Less Harmful than its Remedies?

Some governments have recently called for international accords restricting the use of preferential taxes targeted to attract mobile tax bases from abroad. Are such agreements likely to discourage tax competition or conversely cause it to spread? We study a general model of competition for multiple tax bases and establish conditions for a restriction on preferential regimes to increase or decrease tax revenues. Our results show that restrictions are most likely to be desirable when tax bases are on average highly responsive to a coordinated increase in tax rates by all governments, and when tax bases with large domestic elasticities are also more mobile internationally. Our analysis allows us to reconcile the apparently contradictory results, derived from analyzing special cases, of the previous literature.preferential taxation, tax competition, multiple tax bases
