The factors affecting the international judgement of the Forint and Zloty in the light of the financial crisis of year 2008

The financial crisis of 2007-2009 has shaken both money and capital markets. Its consequences have not even left European markets untouched and divided spirits in the financial world. In some countries efforts by the monetary policy to protect the national currency throughout the crisis seemed to be ineffective. In the present paper we are investigating the effect of the most important macroeconomic and economic policy factors on the exchange rate of the forint and zloty in the last decade. For an analysis of exchange rates we are relying on some preceding research results based on equilibrium exchange rate theories.

Válság és hitelderivatívák. A szintetikus fedezett adósságkötelezettségek (CDO-k) árazása és kockázataik (Crisis and loan derivatives. The pricing and risks of synthetic collateralized debt obligations)

A dolgozat első részében röviden áttekintjük a 2007-ben kezdődött pénzügyi válság lefolyását és a válsághoz vezető okokat. A bemutatás során igyekszünk végig a mögöttes folyamatokra és azok mozgatórugóira koncentrálni, ezzel megragadva a válság egyfajta "elméletét". A bemutatásból láthatóvá válik a hitelderivatívák kiemelt szerepe a válság során. A dolgozat második részében az egyik legnépszerűbb hitelderivatív termék, a szintetikus fedezett adósságkötelezettségek (CDO-k) matematikai modellezését és annak problémáit mutatjuk be. Sokak szerint ezek a matematikai modellek okozták - vagy legalábbis felerősítették - a válságot. Az elemzés során megmutatjuk, hogy nemcsak a modellezési eszközök nem voltak megfelelők, hanem az árazás elve sem állta meg a helyét a kockázatsemleges árazási keretben. Ez az eredmény élesen rámutat a mögöttes elméletek válságára. / === / The first part of the paper examines briefly the financial crisis of 2007 and its causes, focusing on its driving processes and key motifs. This shows clearly the importance and centrality of credit derivatives in the crisis. The second part presents a mathematical modelling of one of the most popular credit derivative products: synthetic collateralized debt obligations, along with the drawbacks and problems of the modelling process. It is widely claimed that these products caused or at least precipitated the crises. The authors show not only that the modelling tools were inappropriate, but that the principle for pricing did not match adequately the risk-neutral valuation framework.

Válságkezelés Európában: új gazdaságfilozófia felé? (Towards a New Philosophy of Crisis Management in Europe?)

Az évek óta tartó európai válságkezelés leírása és a részletek bemutatása helyett a rögtönzött, politikai alapon hozott lépések gazdaságelméleti értelmezésére törekszünk. Kutatási alapkérdésünk a következő: igaz-e még a 70-es évek végének felismerése, ami szerint sem szerkezeti, sem szabályozási eredetű válságot nem lehet keresletélénkítéssel leküzdeni? Igaz-e, hogy a szuverén EU-tagállamokon belül bármi okból hiányzó belső elköteleződést nem lehet pótolni a külső fegyelmezéssel? Ennek fényében vizsgáljuk a költségvetési és a bankunió 2012 októberében körvonalazott és jóváhagyott tervezetét is. _____ This paper attempts to provide a theoretical interpretation of new policy initiatives in the EU culminating in the launching of a fiscal and banking union in June, 2012. This step is reinforced by the new ECB strategy launched in September 2012. These measures were a result of a series of policy improvisations rather than of any secret master plan, still they add up to a new model of European integration. Our research question is if, and to what degrees the insights from the crisis of the 1970s hold. Accordingly no amount of easy money may remedy ills deriving from regulatory and structural inefficiencies. Second, we contend that no amount of external straightjacket/disciplining may replace domestic commitment of national governments in implementing structural reforms rather than fiscal adjustments on the margin.

The efficiency of remanufacturing in a dynamic input–output model

For industrialised economy of ourdays, remanufacturing represents perhaps the largest unexploited resource and opportunity for realising a greater growth of the economy in an environmental-conscious manner. The aim of this paper is to investigate of the impact of remanufacturing in the economy from an economic-efficiency point of view. In static context this phenomenon was analysed in the literature. We use the multi-sector input–output framework in a dynamic context to study intra-period relationships of the sectors of economy. We extend the classical dynamic input–output model taking into consideration the activity of remanufacturing .We try to answer the question, whether the remanufacturing/reuse increases the growth possibility of an economy. We expose a sufficient condition concerning the effectivity of an economy with remanufacturing. By this evaluation we analyse a possible sustainable development of the economy on the basis of the product recovery management of industries.

Tanulságok a gazdasági és monetáris unió számára a 2008-as világgazdasági válság kapcsán (Lessons for the Economic and Monetary Union from the 2008 global economic crisis)

Írásunkban a 2008-ban kitört világgazdasági válságnak a Gazdasági és Monetáris Unióra gyakorolt hatásait elemezzük. Tanulmányunkban rávilágítunk a Gazdasági és Monetáris Unió két olyan problémájára, amelyek a válság után váltak igazán nyilvánvalóvá. Egyrészt a görög államcsődveszély, illetve egyes, korábban jól teljesítő országok botladozása jelzi, hogy a Monetáris Unió intézményrendszere legalábbis hiányos. A másik kérdés összefügg az előzővel, és azon országok szemszögéből érdekes, amelyek csatlakozni kívánnak a GMU-hoz: felerősödtek azok a vélemények, amelyek a csatlakozás elhalasztása mellett foglalnak állást. Tanulmányunk második részében ezt a kérdést járjuk körbe. / === / In our paper we are analyze the effects of the economic crisis of 2008 on the Economic and Monetary Union. We are focusing on two core problems of the EMU which came to surface only after the outbreak of the crisis. First, we address the fiscal problems of Greece and other member states which performed well before the crisis. These problems show that there are major institutional shortcomings in the Monetary Union. The second question is connected to the first one and concerns the new member states of the European Union and their strategies to join the Euro zone. After the crisis more and more voices in the new member states suggest postponing EMU membership.

Rules-based economic governance in the European Union: A reappraisal of national fiscal rules.

The economic and financial crisis of 2007/2009 has posed unexpected challenges on both the global and the regional level. Besides the US, the EU has been the most severely hit by the current economic crisis. The financial and banking crisis on the one hand and the sovereign debt crisis on the other hand have clearly shown that without a bold, constructive and systematic change of the economic governance structure of the Union, not just the sustainability of the monetary zone but also the viability of the whole European integration process can be seriously undermined. The current crisis is, however, only a symptom, which made all those contradictions overt that were already heavily embedded in the system. Right from the very beginning, the deficit and the debt rules of the Maastricht Treaty and the Stability and Growth Pact have proved to be controversial cornerstones in the fiscal governance framework of the European Economic and Monetary Union (EMU). Yet, member states of the EU (both within and outside of the EMU) have shown an immense interest in adopting numerical constraints on the domestic level without hesitation. The main argument for the introduction of national fiscal rules was mostly to strengthen the accountability and credibility of national fiscal policy-making. The paper, however, claims that a relatively large portion of national rules were adopted only after the start of deceleration of the debt-to-GDP ratios. Accordingly, national rules were hardly the sole triggering factors of maintaining fiscal discipline; rather, they served as the key elements of a comprehensive reform package of public budgeting. It can be safely argued, therefore, that countries decide to adopt fiscal rules because they want to explicitly signal their strong commitment to fiscal discipline. In other words, it is not fiscal rules per se what matter in delivering fiscal stability but a strong political commitment.

Volt-e likviditási válság? Volatilitás és likviditás kapcsolatának vizsgálata (Was there a liquidity crisis? Analysis the relationship between volatility and liquidity)

Széleskörűen alátámasztott, empirikus tény, hogy önmagában a nagyobb volatilitás csökkenti a piac likviditását, vagyis változékonyabb piacokon várhatóan nagyobb lesz egy-egy tranzakció áreltérítő hatása. Kutatásomban azt a kérdést vizsgáltam, hogy a Budapesti Értéktőzsdén az OTP-részvény piacán a 2007/2008-as válságban tapasztalható, átmeneti likviditáscsökkenés betudható volt-e egyszerűen a megnövekedett volatilitásnak, vagy ezen túl abban más tényezők (pl. a szereplők körének és viselkedésének drasztikus megváltozása, általános forráscsökkenés stb.) is szerepet játszhattak-e. A volatilitást a loghozamok szórásával, illetve a tényleges ársávval, míg az illikviditást a Budapesti Likviditási Mértékkel (BLM) reprezentáltam. Egyrészt azt állapítottam meg, hogy az OTP esetében a tényleges ársáv szorosabban korrelál a BLM-mel, mint a szórás. Másrészt az is egyértelmű, hogy a válság előtti kapcsolat a volatilitás és a likviditás között a válságban és azután már jelentősen megváltozott. Válságban az illikviditás jóval nagyobb volt, mint amit a volatilitás növekedése alapján vártunk, a válság lecsengése után azonban megfordult ez a reláció. _________ It is a widely supported empirical fact, that the greater volatility in itself decreases the liquidity of the market, namely more volatile a market is, the higher a transaction’s price impact will be. I have examined in my paper the question, whether the decrease of liquidity during the crisis of 2007/2008 in case of the OTP stock – traded on the Budapest Stock Exchange – was the consequence of the increased volatility, or other factors had an effect on the illiquidity as well (e.g.: the drastic change of market participants’ behaviour; reduction of fi nancing sources; etc.). I have represented volatility with the standard deviation of the logreturns, and with the true range, while the illiquidity with the Budapest Liquidity Measure (BLM). On one hand I have identifi ed, that in case of the OTP, the true range has a stronger relationship with the BLM than the standard deviation has. On the other hand it was clear, that the relationship between volatility and liquidity has changed notably during and after the crisis. During crisis the illiquidity was greater than what I have estimated based on the volatility increase, but after the crisis this relation has changed.

Developmental perspectives on Europe

The crisis of 2008–2009 has ended, stockmarkets skyrocketed in 2012–2013, while growth of the real sector remained sluggish in Europe. This article attempts to explain the latter puzzle. Analyzing long term factors, the costs of short-termism in crisis management become obvious. The limitations of EU as a growth engine are highlighted.

Banking Contagion under Different Exchange Rate Regimes in CEE

The global crisis of 2008 caused both liquidity shortage and increasing insolvency in the banking system. The study focuses on credit default contagion in the Central and Eastern European (CEE) region, which originated in bank runs generated by non-performing loans granted to non-financial clients. In terms of methodology, the paper relies on one hand on review of the literature, and on the other hand on a data survey with comparative and regression analysis. To uncover credit default contagion, the research focuses on the combined impact of foreign exchange rates and foreign private indebtedness.

Implicit rating: A potential new method to alert crisis on the interbank lending market

A new measure called “implicit rating” is introduced which might be a component of an early warning system. The proposed methodology relies on the aggregation of experts’ knowledge hidden in the transactional data of the interbank market of unsecured loans. Banks are simultaneously assessing the creditworthiness of each other which is reflected in the partner limits and in the interest rates. In the Hungarian interbank market the overall trading volume and the average interest rate did not show any negative trends before the crisis of 2008, however the average implicit partner limit started to decrease several months earlier, hence it might serve as a stress indicator.
