A new family of kernels is suggested for use in heteroskedasticity and autocorrelation consistent (HAC) and long run variance (LRV) estimation and robust regression testing. The kernels are constructed by taking powers of the Bartlett kernel and are intended to be used with no truncation (or...

Separating seasonal components from other sources of economic fluctuations is crucial for both economic modeling and policy making. Practitioners treat seasonality as noise to be removed before estimating models and tend to apply deseasonalizing methods i

Numerous empirical studies have shown evidence of nonlinearities in financial time series, which can be of both a deterministic and a stochastic nature. Chaos is an example of the former, and heteroscedasticity in the conditional variance an example of the latter. We apply a test, the BDS test,...

A 2008-ban kitört pénzügyi válság ráirányította a figyelmet a mainstream makroökonómiára, amely a válság elõrejelzésében és magyarázatában rossz teljesítményt nyújtott. Az újklasszikus és az újkeynesi iskola közötti konszenzus eredményeként létrejött DSGE-modellek...

This paper improves the analysis of the role of financial frictions in the transmission of monetary policy, by bringing together the borrowers' balance sheet channel with an additional channel working through bank capital, considering capital adequacy regulations and households' preferences for...

We study the effects of German unification in a model with capital accumulation, skill differences and a welfare state. We argue that this event is similar to a mass migration of low-skilled agents holding no capital into a foreign country. Absent a welfare state, we observe an investment boom,...

In our dynamic optimizing sticky price model, agents are heterogenous with regard to their assets and their income. Unanticipated inflation redistributes income and wealth. In order to model the wealth distribution, we study a 60-period OLG model with aggregate uncertainty. A positive technology...

A cikkben a szerzõk azt vizsgálják, hogy az EU-hoz 2004 óta csatlakozott tizenkét új tagállam az euróövezethez való csatlakozás szempontjából milyen mértékben felel meg az optimális valutaövezet elmélete (Optimal Currency Area, OCA) által támasztott kritériumoknak. Fõ...

Built upon data from 11 subsequent waves of yearly wage surveys carried out by the National Labour Center in Hungary from 1992 to 2003, the paper examines, with the use of elementary statistical tools, whether or not earnings fluctuations differed in size among groups of employees with different...

This study explores office market cycles based on five office market indicators. We analyze time series of yield, take-up, vacancy, rent and new supply on a worldwide database, which is more detailed than any other used previously, as it comprises of data about nearly one hundred cities. Yields...
