Estimated labor supply functions are important tools when designing an optimal income tax or calculating the effect of tax reforms. It is therefore of large importance to use estimation methods that give reliable results and to know their properties. In this paper Monte Carlo simulations are...

Macroeconomic studies of tax policy in dynamic general equilibrium usually assume that reforms hit the economy unexpectedly and last forever. Here, we explore how previous results change when we allow policy changes to be pre-announced and of finite duration and when these facts are anticipated...

We develop a tax micro-simulator model (MEXTAX) that can quantify the revenue and distributional impact of tax reforms in Mexico using micro-level data. We use MEXTAX to assess revenue-raising reforms to Mexico's direct and indirect tax systems of 2010. Initial proposals by the Executive Power...

Der Abbau der kalten Progression wird aktuell wieder diskutiert. An einigen Eckwerten des Einkommensteuertarifs lässt sich zeigen, dass die tatsächliche Entwicklung deutlich von den zum Ausgleich der Inflation erforderlichen Tarifänderungen abweicht. Die Autoren berechnen die Mindereinnahmen...

In 2005, the German government announced a far-reaching fiscal adjustment program. This paper uses the IMF's Global Fiscal Model to study its impact and explores options for addressing long-term pressures from population aging. The growth effects of the planned VAT increase are likely modest,...

One of the most striking tax developments in recent years, and one that continues to attract considerable attention, is the adoption by several countries of a form of 'flat tax'. Discussion of these quite radical reforms has been marked, however, more by assertion and rhetoric than by analysis...

Tax administration plays a crucial role in determining a country`s real (or effective) tax system. Unfortunately, tax administrations in many countries do not function optimally and distort the intention of tax laws. In order for taxation to have its intended effect on the allocation of...

The Sri Lankan government implemented tax reforms in 2011, including removal of the tax exemption given to public servants and reduction of personal income tax rates in order to improve tax compliance from pay-as-you-earn (PAYE) tax payers. This study evaluates the 2007 and 2011 tax systems in...
