The literature on economics of transition has suggested a number of scenarios to explain unemployment and labour reallocation in Eastern Europe. However, it has recently been argued that these so-called Optimal Speed of Transition (OST) studies do not account for many stylized facts concerning...

This work revisits the role of regulations in emergence o f the shadow economy. In particular, it supplements the previous theoretical research that mainly ignored the fact that the decision to “go underground” is essentially a result of both employers and employees interacting in the labour...

This paper analyses the emergence of the informal economy in the environment characterised by non-competitive labour markets with wage bargaining. We develop a simple extension of the standard search model à la Pissarides (2000) with formal and informal sectors to show how a government’s...

This work suggests a development of the seminal model of transition from plan to market economy by Aghion and Blanchard (1994). We introduce an informal sector to show that its presence can generate qualitatively di?erent steady states, to which the economy converges in the end of transition....

We consider the problem of finding a valid covariance matrix in the FX market given an initial non-PSD estimate of such a matrix. The standard no-arbitrage assumption implies additional linear constraints on such matrices, which automat-ically makes them singular. As a result, one cannot just...

A number of methods has already been proposed for creating a valid correlation matrix in finance. However, such methods do not normally take into account additional restrictions on matrix elements imposed by specific non-arbitrage conditions in some markets, e.g. foreign exchange (FX). I suggest...
