Efficiency and the trading system:The case of SETSmm

This paper studies the impact that a change from a dealer system to a market-maker supported auction system has on market quality. We study the impact that the introduction of SETSmm at the London Stock Exchange had on firm value, price efficiency and liquidity. We discover a small SETSmm return premium associated with the announcement that securities are to migrate to the new trading system. Moreover, securities that migrate to SETSmm are characterized by improvements to liquidity and pricing efficiency. We find that these changes are related to the return premium.

Wealth shocks, credit-supply shocks, and asset allocation:evidence from household and firm portfolios

We use a unique dataset with bank clients’ security holdings for all German banks to examine how macroeconomic shocks affect asset allocation preferences of households and non-financial firms. Our analysis focuses on two alternative mechanisms which can influence portfolio choice: wealth shocks, which are represented by the sovereign debt crisis in the Euro area, and credit-supply shocks which arise from reductions in borrowing abilities during bank distress. While households with large holdings of securities from stressed Euro area countries (Greece, Ireland, Italy, Portugal, and Spain) de-crease the degree of concentration in their security portfolio as a result of the Euro area crisis, non-financial firms with similar levels of holdings from stressed Euro area countries do not. Credit-supply shocks at the bank level result in lower concentration, for both households and non-financial corporations. Only shocks to corporate credit bear ramifications on bank clients’ portfolio concentration. Our results are robust to falsification tests, and instrumental variables estimation.

Portfolio size, non-trading frequency and portfolio return autocorrelation

In this paper we re-examine the relationship between non-trading frequency and portfolio return autocorrelation. We show that in portfolios where security specific effects have not been completely diversified, portfolio autocorrelation will not increase monotonically with increasing non-trading, as indicated in Lo and MacKinlay (1990). We show that at high levels of non-trading, portfolio autocorrelation will become a decreasing function of non-trading probability and may take negative values. We find that heterogeneity among the means, variances and betas of the component securities in a portfolio can act to increase the induced autocorrelation, particularly in portfolios containing fewer stocks. Security specific effects remain even when the number of securities in the portfolio is far in excess of that considered necessary to diversify security risk. © 2014 Elsevier B.V.

The effect of timeliness and credit ratings on the information content of earnings announcements

Abstract: This paper investigates the impact of timeliness and credit ratings on the information content of the earnings announcements of Greek listed firms from 2001 to 2008. Using the classical event study methodology and regression analysis, we find that firms tend to release good news on time and are inclined to delay the release of bad news. We also provide evidence that the level of corporate risk differentiates the information content of earnings according to the credit rating category. Specifically, firms displaying high creditworthiness enjoy positive excess returns on earnings announcement dates. In contrast, firms with low creditworthiness undergo significant share price erosions on earnings announcement days. We also observe a substitution effect between timeliness and credit ratings in relation to the information content of earnings announcements. Specifically, we find that as the credit category of earnings-announcing firms improves, the informational role of timeliness is mitigated.

Wealth shocks, credit-supply shocks, and asset allocation:evidence from household and firm portfolios

We use a unique dataset with bank clients’ security holdings for all German banks to examine how macroeconomic shocks affect asset allocation preferences of households and non-financial firms. Our analysis focuses on two alternative mechanisms which can influence portfolio choice: wealth shocks, which are represented by the sovereign debt crisis in the Eurozone, and credit-supply shocks which arise from reductions in borrowing abilities during bank distress. We document het- erogeneous responses to these two types of shocks. While households with large holdings of secu- rities from stressed Eurozone countries (Greece, Ireland, Italy, Portugal, and Spain) decrease the degree of concentration in their security portfolio as a result of the Eurozone crisis, non-financial firms with similar levels of holdings from stressed Eurozone countries do not. Credit-supply shocks at the bank level (caused by bank distress) result in lower concentration, for both households and non-financial corporations. We also show that only shocks to corporate credit bear ramifications on bank clients’ portfolio concentration, while shocks in retail credit are inconsequential. Our results are robust to falsification tests, propensity score matching techniques, and instrumental variables estimation.

Out of credit: Evaluating the impact of the EU structural funds on Hungarian small business growth and access to finance

Totaling EUR 29 billion, Hungary is in the midst of implementing its largest economic development program in its young democratic history. At the center of the European Union led development program is an effort to revitalize and reequip Hungary’s languishing small and medium sized enterprises (SME), long the country's heart of employment. This paper examines the efficiency and impact of two Structural Fund's instruments to enhance SME development – ECOP 2.1.1 and JEREMIE. A survey of 1275 SME and interviews with dozens of top policy-makers paint a flawed development program in dire need of reform. Despite this, empirical analysis suggests JEREMIE funds may have dampened the effects of the financial crisis and are crucial for the continued liquidity of SME, who have been particularly hit hard by the world financial crisis.

Megtakarítások és külső finanszírozás az amerikai gazdaságban. A hitelpiaci válság háttere (1997-2007) (Savings and external financing in the American economy. The background to the credit-market crisis (1997–2007))

A tanulmány nem az aktuális hitelpiaci válság enyhítésének kérdésével foglalkozik, hanem az amerikai gazdaság elmúlt négy évtizedének általános és az utolsó tíz évének konkrét beruházási-megtakarítási és növekedési tendenciáit igyekszik feltárni. Azt vizsgálja, hogy milyen mélyebb, belföldi eredetű szerkezeti okai vannak a nemzetközivé dagadt jelzáloghitel-válságnak. A cikk a nyitott gazdaság külső finanszírozással összefüggő mérlegazonosságainak alapján arra a következtetésre jut, hogy az ingatlanpiaci visszaesés és a kibocsátás zsugorodása az Egyesült Államok gazdaságában már több mint másfél évtizede kialakult kedvezőtlen, de még tovább romló belföldi megtakarítási folyamatok következménye. A jelzálogpiac krízise és a lakásépítés drámai visszaesése a túlfogyasztásra és túlhitelezésre ösztönző pénzügyi környezet eredménye. A lakáspiaci és a hitelezési ciklusok pénzügyi innovációkkal történő megnyújtása inkább növelte, mint csökkentette a kibocsátásingadozás érzékenységét. A legfőbb hitelezők Kína, Japán, Németország inkább dolláralapú amerikai vállalati felvásárlásokkal ellensúlyozták a dollárgyengülésből elszenvedett veszteségeiket. 1997-2007 között az Amerikából külföldön befektetett dolláraktívák - javarészt a valuta leértékelődése nyomán - jelentős hozamemelkedést élveztek, és számottevően tompították a belföldön képződött jövedelmek csökkenését. A dollárleértékelődés az eszköz- (és nemcsak az áruexport) oldalon is előnyöket hozott számos nagyvállalatnak. / === / Rather than dealing with the immediate policy steps to dampen the crisis, this paper attempts to reveal the worsening savings/consumption pattern of the US economy over the last ten years. Based on the closed logic of open-economy GDP-accounting, it argues that the current crisis is deeply rooted in shrinking public and private savings trends discernible as early as 1997. The current mortgage-market crisis and deep fall in new residential housing are products of a distorted financial environment that encourages over-borrowing and over-consumption. Expansion of the credit cycle through successive financial innovations has increased, not decreased output volatility. But the main foreign lenders to the US—Japan, China and Germany—have managed to offset their losses on US securities by buying into US companies. Large US firms have also benefited from rapid dollar depreciation as USD-denominated yields on their foreign assets experienced strong run-ups. The weak dollar has also helped American firms with large assets on foreign markets. So there were strong benefits for the US, not just on the goods-export side, but on the asset side, an aspect rarely emphasized.

Az agrárkereskedelem változása Magyarország és az Európai Unió között a csatlakozás után (The post-accession change in agricultural trading between Hungary and the EU)

2004-ben Magyarország kilenc közép-kelet-európai országgal együtt csatlakozott az Európai Unióhoz, ami számos változást idézett elő az agrárkereskedelem terén. A cikk célja, hogy a legfrissebb adatok és a szakirodalmi fejlemények tükrében bemutassa, hogyan alakult Magyarországon a mezőgazdasági alapanyagok és a feldolgozott termékek kereskedelme az Európai Unióval. A megnyilvánuló komparatív előnyök módszerét alkalmazva a cikk számos következtetésre jutott. Először is világossá vált, hogy a csatlakozás növelte az agrárkereskedelem intenzitását, ám negatív hatással volt a kereskedelem egyenlegére. Kimutatható továbbá, hogy Magyarország az alacsony hozzáadott értékű alapanyagexportra és a magas hozzáadott értékű feldolgozott termékek importjára koncentrált a csatlakozás után, noha ezek komparatív előnyei nagymértékben megváltoztak egy hatékony alkalmazkodási folyamat következtében. A változások tényét támasztják alá a különböző rövid és hosszú távú stabilitásvizsgálatok is, amelyek az agrártermékek megnövekedett versenyére utalnak az EU-15 piacán. Agrárpolitikai szempontból az elemzések alátámasztják a strukturális reformok szükségességét. / === / Numerous changes in agricultural trading from the EU accession of Hungary and nine other Central-East European countries in 2004. The article sets out to present, in the light of the latest figures and written contributions, how Hungary’s EU trade in agricultural raw and semi-processed products developed thereafter. It uses the method of manifest comparative advantages to reach its conclusions. First, it became clear that accession increased the intensity of agricultural trading, although it had a detrimental effect on the trade balance. It also appeared that post-accession Hungary was concentrating on exports of basic materials of low added value and imports of processed articles with high added value, although these comparative advantages were much altered by an effective process of adaptation. The fact of the changes is supported by various short and long-term stability examinations, which point to increased competition for agricultural products on EU15 markets. From the policy point of view, the analyses support the need for structural reforms.

Analyzing interrelated stochastic trend and seasonality on the example of energy trading data

The correct modelling of long- and short-term seasonality is a very interesting issue. The choice between the deterministic and stochastic modelling of trend and seasonality and their implications are as relevant as the case of deterministic and stochastic trends itself. The study considers the special case when the stochastic trend and seasonality do not evolve independently and the usual differencing filters do not apply. The results are applied to the day-ahead (spot) trading data of some main European energy exchanges (power and natural gas).
