This paper reviews the meaning and measurement of unobserved economies germane to tax evasion and macroeconomic information systems. These include the unreported, non-observed, underground, illegal, informal and unrecorded economies. It reviews the progress and shortcomings of national and...

Professor Schneider's “Comment” on my “Reflections” paper does not adequately address the key issues concerning the veracity of his findings, namely issues of documentation, normalization, calibration and replication. Further findings of inadequate documentation, suspicious normalization...

This paper examines the relationship between corruption and public debt in 106 countries. Results suggest that corruption leads to an increase in public debt. We also investigate if the effect of corruption on pblic debt is increased by government expenditure, the shadow economy and military...

This comment provides a reply to Prof. Feige's paper with the title “Reflections on the Meaning and Measurement of Unobserved Economies: What do we really know about the ‘Shadow Economy'?”, in which Prof. Feige heavily criticizes me. I show that the same critique which Prof. Feige raises...

Some authors argue that informality is associated with distorted firm decisions and inefficiency. In this paper, I assess the quantitative effect of incomplete tax enforcement on aggregate output and productivity using a dynamic general equilibrium framework. I calibrate the model using data for...

This paper examines how trade sanctions affect the allocation of workers across formal and informal employment. We analyse the case of the unexpected and unprecedented trade sanctions imposed on Iran in 2012. We use a difference-in-differences approach and compare the probability of working in...

The aim of this paper is to quantify the role of formal-sector institutions in shaping the demand for human capital and the level of informality. We propose a firm dynamics model where firms face capital market imperfections and costs of operating in the formal sector. Formal firms have a larger...

This paper investigates the response of the shadow economy to banking crises. Our empirical analysis, based on a large sample of countries, suggests that the informal sector is a powerful buffer, which expands at times of banking crises and absorbs a large proportion of the fall in official...

We build a general equilibrium model in which both illegal immigration and the size of the informal sector are endogenously determined. In this framework, we show that indirect policy measures such as tax reduction and detection of informal activities can be used as substitutes for border...
