In December 2016 the National Bank of Hungary (NBH), by referring to its "backcasts" (based on analyses of past data-revisions), arbitrarily revised upwards the data of the Hungarian Statistical Office (HSO) on GDP-growth for the first three quarters of 2016. This "methodological innovation" (as...

We scrutinise in this paper the systemic consequences of state intervention triggered by external shocks for the dynamics of investment in the transforming Chinese economy. Our analysis focuses on the period before and after the global crisis. We interpret investment dynamics in a comparative...

A great deal of multinationals receive a bundle of hidden or cash subsidizes upon investing in a foreign country. Policymakers often argue that a subsidy today will help locate friends of the investor later on. Using extensive data on FDI investments, we analyze such patterns. In particular, we...

Using firm-level microdata, our study investigates the heterogeneity of three types of taxes levied on firms (corporate tax, payroll tax and local business tax). We show that business taxes per worker and per unit value added significantly differs among different types of firms and that tax...

The article uses continuous wavelet analysis for the study of certain export-import time series. It is a novel methodology, with the promise, inter alia, to detect features of processes that may remain hidden for traditional methodologies. The application of wavelets has been rapidly increasing...

In his seminal model (Feldstein, 1985), the government operates a social security system to counter the representative worker's myopia. (i) For a complete myope, he determined a sizable optimal tax rate (and the corresponding benefit level). (ii) For a partially shortsighted worker, he...

We are given a bipartite graph G = (A B;E) where each vertex has a preference list ranking its neighbors: in particular, every a A ranks its neighbors in a strict order of preference, whereas the preference list of any b B may contain ties. A matching M is popular if there is no matching M' such...

We study a natural generalization of the maximum weight many-to-one matching problem. We are given an undirected bipartite graph G = (A P, E) with weights on the edges in E, and with lower and upper quotas on the vertices in P.We seek a maximum weight many-to-one matching satisfying two sets of...

Given a bipartite graph G=(A B, E) with strict preference lists and given an edge e E, we ask if there exists a popular matching in G that contains e. We call this the popular edge problem. A matching M is popular if there is no matching M' such that the vertices that prefer M' to M outnumber...

We consider two variants of the classical Stable Roommates problem with Incomplete (but strictly ordered) preference lists (SRI) that are degree constrained, i.e., preference lists are of bounded length. The first variant, egal d-SRI, involves finding an egalitarian stable matching in solvable...
