11.1 Globalization and Tax Competition

Globalization has sparked fierce tax competition among nations, leading to a "race to the bottom" in corporate tax rates. As capital and labor become more mobile, governments struggle to set tax policies independently, while multinational corporations exploit loopholes to minimize their tax bills.

International organizations are fighting back with initiatives to curb harmful tax practices and promote fair competition. The OECD's BEPS project and efforts to implement a global minimum corporate tax rate aim to level the playing field, but face challenges in balancing national interests and economic realities.

• Globalization intensified tax competition among countries led to a "race to the bottom" in corporate tax rates
• Mobility of capital and labor in globalized economy constrains governments' ability to set tax policies independently
• Tax havens and preferential tax regimes emerged due to increased global competition for investment and tax revenues
• Multinational corporations engage in profit shifting and tax planning strategies to minimize global tax liabilities
  • Transfer pricing manipulation
  • Strategic location of intellectual property
• Digitalization of economy created new challenges for taxing cross-border transactions and digital services
  • Difficulty in determining taxable presence for digital companies
  • Issues with characterization of income from digital transactions

Government Responses and International Initiatives

• Governments face pressure to balance attracting foreign investment with maintaining sufficient tax revenues for public services
  • Offering tax incentives to attract multinational corporations
  • Implementing anti-avoidance measures to protect tax base
• International organizations developed guidelines and initiatives to address harmful tax practices and promote fair tax competition
  • OECD's Harmful Tax Practices initiative
  • EU's Code of Conduct for Business Taxation

Challenges of International Tax Coordination

OECD Initiatives and Tax Treaties

• OECD's Base Erosion and Profit Shifting (BEPS) project combats tax avoidance strategies used by multinational enterprises
  • 15 action items addressing various aspects of international taxation
  • Implementation through Inclusive Framework with over 135 countries
• Bilateral and multilateral tax treaties facilitate information exchange and reduce double taxation
  • Creates opportunities for treaty shopping (using intermediary entities in favorable treaty jurisdictions)
• Global minimum corporate tax rate presents opportunities for revenue stability and challenges for national sovereignty
  • Proposed 15% minimum rate under OECD Pillar Two
  • Concerns about impact on tax competition and investment flows

Tax Transparency and Digital Taxation

• Coordinated efforts to enhance tax transparency improve tax compliance but raise privacy concerns
  • Common Reporting Standard (CRS) for automatic exchange of financial account information
  • Country-by-Country Reporting for large multinational enterprises
• Development of digital taxation frameworks addresses new economic realities but faces opposition
  • EU's proposed Digital Services Tax
  • Unilateral measures implemented by countries (France's Digital Services Tax)
• International tax coordination efforts must balance interests of developed and developing countries
  • Considering different economic structures and priorities
  • Addressing concerns about fair allocation of taxing rights
• Effectiveness of tax coordination initiatives depends on widespread adoption and consistent implementation across jurisdictions
  • Challenges in achieving global consensus
  • Issues with enforcement and monitoring compliance

Tax Competition and Foreign Investment

Impact of Tax Rates on FDI

• Lower corporate tax rates and targeted tax incentives often used to attract foreign direct investment (FDI)
  • Examples: Ireland's 12.5% corporate tax rate, Singapore's tax incentives for specific industries
• Tax competition can lead to more efficient allocation of capital globally
  • Potentially results in suboptimal levels of public goods provision
• Sensitivity of FDI to tax rates varies across industries
  • More mobile sectors (technology, finance) show higher elasticities
  • Less mobile sectors (natural resource extraction) show lower elasticities
• Tax competition influences location decisions of multinational corporations
  • Potentially leads to economic distortions (artificial shifting of economic activity)

Factors Influencing FDI and Tax Competition

• Effectiveness of tax incentives in attracting FDI depends on other factors
  • Infrastructure quality
  • Market size and growth potential
  • Political stability and regulatory environment
• Tax competition can result in shift from source-based taxation to residence-based taxation
  • Affects distribution of tax revenues among countries
  • Challenges traditional concepts of international taxation
• Concept of "effective tax rates" crucial in understanding how tax competition influences FDI flows
  • Accounts for both statutory rates and tax base definitions
  • Examples: Marginal Effective Tax Rate (METR), Average Effective Tax Rate (AETR)

Distributional Effects of Tax Competition

Impacts on Income Groups and Labor

• Tax competition often shifts tax burden from mobile factors (capital) to less mobile factors (labor)
  • Potentially increases income inequality
  • Examples: Reduction in corporate tax rates coupled with increases in payroll taxes
• Reduction in corporate tax rates may benefit shareholders and high-income individuals more than lower-income groups
  • Through increased dividends and capital gains
  • Potential exacerbation of wealth concentration
• Small and medium-sized enterprises (SMEs) may be at disadvantage compared to multinational corporations
  • Limited ability to exploit international tax planning opportunities
  • Higher effective tax rates for SMEs compared to large multinationals

Sectoral and Regional Effects

• Tax competition can lead to narrowing of tax base
  • Potentially results in reduced public spending or increased taxes on consumption and property
  • Examples: Increases in VAT rates or property taxes to compensate for corporate tax revenue losses
• Certain sectors may benefit more from tax competition due to higher mobility and ability to shift profits
  • Manufacturing (through transfer pricing)
  • Digital services (through strategic location of intellectual property)
• Erosion of corporate tax base may lead to increased reliance on other forms of taxation
  • Value-added taxes (potentially regressive)
  • Environmental taxes
• Tax competition can exacerbate regional disparities within countries
  • Some regions better positioned to attract mobile capital through tax incentives
  • Examples: Special economic zones or regional tax incentives creating "winner" and "loser" regions
