This paper develops a labour market matching model in order to address the problem of the persistence of the hidden sector and of its regional concentration, as in Italy and in the enlarged Europe. The main novel features of the model are that entrepreneurial ability affects job productivity,...

The paper reexamines the strengths and weakness of all direct and indirect methods of estimating the amount of US currency held abroad and concludes that between 25% -45% of US currency is held abroad. This result stands in sharp contrast to the widely cited estimates presented by Porter and...

How do government-supplied institutional benefits and the taxation and regulation of producers affect the propensity of private�firms to enter the unofficial economy and evade taxation? We propose a model in which the incentive of firms to operate underground depends on tax rates relative to...

Relying on the non-negligible role played by the underground economy in the labour market fluctuations, this paper extends the standard matching model à la Mortensen-Pissarides by introducing an underground sector along with an endogenous sector choice for both entrepreneurs and workers. These...

A matching model will explain both unemployment and economic growth by considering the underground sector. Three problems can thus be simultaneously accounted for: (i) the persistence of underground economy, (ii) the ambiguous relationships between underground employment and unemployment, and...

This note empirically investigates the impact of various factors on income tax evasion in the U.S. over the 1973-1997 period. The estimate indicates that income tax evasion is an increasing function of the average effective federal personal income tax rate and the public's dissatisfaction with...

Unaccounted for currency in the U.S. has been argued to reflect the presence of widespread income tax evasion. In turn, income tax evasion is especially problematic in this era of large government budget deficits and growing national debts which have led to debt crises. This empirical study...

This study empirically investigates the impact of a variety of factors on income tax evasion in the United States over the period 1973 to 1997. The aggregate estimates indicate that federal income tax evasion may be an increasing function of the federal personal income tax rate and the...

The paper presents estimations of the informal economy size in Bolivia from an application of a Dynamic General Equilibrium Model. The parameter estimation is performed using maximum likelihood method to obtain, as an intermediate result, a latent variable estimation of the informal economy...

Using new time-series data for the size of the Canadian underground economy, the relationship between unreported and measured GDP in that country is examined. Granger causality tests are conducted, with a proper allowance for the non-stationarity of the data. It is found that there is clear...
