Performance indices are used worldwide as indicators of activity in key sectors to assist analysts and decision-makers. An advantage of these indices is that, by pooling information from the series that make up the indices, idiosyncratic variation is smoothed out, and a stable and potentially...

This paper studies whether trade openness reduces the domestic fiscal multiplier, but increases the impacts of foreign fiscal shocks, i.e., the spillover effect, as suggested by theory. Using annual data from the period of 1970 to 2011, for 179 developed and developing economies, we show that...

I compare the performance of solution methods in solving a standard real business cycle model with labor market search frictions. Under the conventional calibration, the model is solved by the projection method using the Chebyshev polynomials as its basis, and the perturbation methods up to...

We review the theory of leverage developed in collateral equilibrium models with incomplete markets. We explain how leverage tends to boost asset prices, and create bubbles. We show how leverage can be endogenously determined in equilibrium, and how it depends on volatility. We describe the...

Giving up an independent monetary policy and a flexible exchange rate are the key sources of costs and benefits entailed to joining a monetary union. In this paper we analyze their ex post impact on the stability of the Polish economy during the recent financial crisis. To this end we construct...

I present a dynamic fixed cost model of export participation extended by a capital theoretic concept of the customer stock. Plants that want to start exporting have to invest into a market specific factor which serves as input into a decreasing returns to scale technology generating sales...

This chapter analyzes the effect of international trade on the local stability properties of economies in a Heckscher-Ohlin free-trade equilibrium. We formulate a two-factor (capital and labor), two-good (consumption and investment), two-country overlapping generations model where countries only...

A piaci szabályozás stabil, de nem aszimptotikusan stabil, nem konvergens, nem tart egyensúly felé. Több számítási eljárás létezik az egyensúly, illetve az egyensúlyi pálya meghatározására, de ezek nem a piac mozgásának egyenletei. Ha létezik ilyen egyenlet, akkor...

A gazdasági mozgás dualitásának és szimmetriáinak felismerése új felfogást kínál a kutatónak. Mint a múlt századi természettudományban, az "okok" és "célok" vitája elsimul. Ma már nem a látszólag ellentétes paradigmák és iskolák logikai vetélkedése, de a mozgás...

W. Leontief megalkotta a gazdasági növekedés végtelen lineáris modelljét. A számításokat azonban a modell véges szeletével végezzük. Ezt a véges részt többféleképpen is ki lehet választani. Az eredetileg publikált forma a gazdaság felszámolásának nyomvonalát adja meg....
