In the tax literature, the tax effort index for any country is usually measured by the ratio of the actual tax ratio to the predicted ratio. This reflects mainly the variance in the taxable capacity of a country. A high value of tax effort index indicates that a particular country is collecting...

We analyse the deadweight losses of tax-induced labor misallocation in an equilibrium model of the labour market where workers search to climb a job ladder and firms post vacancies. Workers differ in abilities. Jobs differ in productivities and amenities. A planner uses affine tax functions to...

This paper provides a general equilibrium model of income tax evasion. As functions of the share of income reported, the paper contributes an analytic derivation of the tax elasticity of taxable income, the welfare cost of the tax, and government revenue as a percent of output. It shows how an...

This paper investigates the effect of ICT and e-formalization on tax mobilization efforts in sub-Saharan Africa. Using a panel of 42 countries from 1991 to 2018 and applying appropriate model specifications; the empirical findings show that there is strong support that ICT (mobile subscription...

Revenue from taxation has become more volatile after the global financial crisis. In this paper we provide a mean-variance analysis for key taxation components in the Irish fiscal accounts. This approach is a useful complement to the more standard measures of fiscal developments, which typically...

This paper analyses the reaction of fiscal policy to the cycle in OECD countries. The results suggest that while overall government balances were counter-cyclical in the past and more so in economic downturns than in upswings, discretionary fiscal policy was neutral on average. However,...

In an imperfectly competitive economy with direct and indirect taxes, the first best wage subsidy overcompensates workers and provides the incentive to misreport working hours. We show that in the second best optimum where the government cannot use a wage subsidy, the optimal policy is to tax...

We analyse attempts to implement personalised regulation in the form of sin licenses (O'Donoghue and Rabin 2003, 2005, 2007) to correct the distortion in the consumption of a harmful good when consumers suffer from varying degrees of self-control problems. We take into account the possibility...

Increasing inequality in recent decades has triggered a heated debate on whether wealth transfer taxation is an appropriate countermeasure to the perpetuation of inequality. A major factor in making progress in this discussion is understanding how taxpayers respond to incentives generated by...

In recent years, a series of studies have been undertaken in Australia that use static general equilibrium models with a representative household to compare the relative efficiency of different Australian taxes. This paper aims to complement these earlier studies and contribute to a broader...
