Introduction

This collected volume gives a concise account of the most relevant scientific results of the COST Action IS1104 "The EU in the new complex geography of economic systems: models, tools and policy evaluation", a four-year project supported by COST (European Cooperation in Science and Technology). It is divided into three parts reflecting the different perspectives under which complex spatial economic systems have been studied: (i) the Macro perspective looks at the interactions among international or regional trading partners; (ii) the Meso perspective considers the functioning of (financial, labour) markets as social network structures; and, finally, (iii) the Micro perspective focuses on the strategic choices of single firms and households. This Volume points also at open issues to be addressed in future research

Systemic risk and macroeconomic fat tails

We propose a mechanism for shock amplification that potentially can account for fat tails in the distribution of the growth rate of national output. We argue that extreme macroeconomic events, such as the Great Depression and the Great Recession, were preceded by significant turmoil in the banking system. We have developed a model of bank network formation and presented numerical simulations that show that, for the benchmark case, aggregate credit follows a random walk. When we introduce fire sales the model does not only produce larger variations in the growth of aggregate credit but also shows that there is an asymmetry between booms and busts that is also consistent with empirical evidence

On the nature of banks

Two views exist regarding the nature of the banking business. The dominant view defines banks as financial intermediaries – institutions in the business of transferring money from savers to borrowers. An alternative view advances that banks finance borrowers via money creation. I explain the differences between these two views and argue for the superiority of the latter one as a description of modern banking. I discuss the implications for economic analysis and explain how the connection between bank lending and money creation helps us understand the effects of banking on economic activity

The Euro as a Proxy for the Classical Gold Standard? Government Debt Financing and Political Commitment in Historical Perspective

[Introduction] In spite of the recent troubles in the euro area, Jesus Huerta de Soto (2012), a famous proponent of the gold standard, argues that the euro should be considered a 'second best to the gold standard' and is worth being preserved. From a classical liberal point of view, he sheds some light on the euro's similarities with the gold standard and on some important advantages of the currency union over its alternative, flexible exchange rates in Europe. According to Huerta de Soto (2012), the main advantage of the introduction of the common currency is that - like when 'going on gold' - European governments have given up monetary nationalism. Like the gold standard, the euro limits state power as it prevents national central banks from manipulating exchange rates and inflating away government debt. Currently, he argues, the common currency - like previously the gold standard - forces important reforms and/or spending cuts upon the countries of the euro area that face severe debt and structural problems. In this respect, the euro should be seen as 'a proxy for the gold standard'. In this policy paper, I attempt to address some similarities and differences in the institutional framework of the classical gold standard (1880 - 1912) and the European Monetary Union (EMU) (1999 - ) that affect government debt financing and the way in which countries react to crisis. I argue that - in line with Huerta de Soto (2012) - giving up monetary nationalism and committing to the rules of either the gold standard or EMU initially restricted the scope of state action. Therefore, the euro - like previously the gold standard - provided some (fiscal) policy credibility. Fiscal policy credibility was the main determinant of capital market integration and low government borrowing costs in Europe under both systems. But in contrast to Huerta de Soto (2012), I shall emphasize that neither the gold standard, nor the euro itself force reforms and spending cuts upon countries that face crisis and debt problems. The political commitment to the monetary systems determines the willingness to reform or cut spending and therewith fiscal policy credibility in crisis periods: (...

The Political Economy of Failure: The Euro as an International Currency

How do international currencies get established and consolidated? What domestic and international political foundations support an international currency? And what kinds of macro-economic flows enable an international currency? In this essay we consider these perennial questions of modern IPE scholarship in reverse order to ask whether the euro could ever have become, or seek to become, a true international currency rivalling the US dollar, used not only for passive foreign exchange reserves but also as a major commercial currency outside the EU. We argue that the EU lacks the will, the ideas and the capacity to promote the euro into the status of an international currency. In this article, we concentrate on this final issue of capacity, as the will and ideas issues have already been well explored. Capacity is an issue coeval with, if not prior to, the first two issues. The EU's current institutional arrangements and its economic geography create macro-economic consequences that diminish the euro's capacity to operate as a top currency. These conflicts go beyond the well-recognized issue that the euro-zone is not an optimum currency area. Examining the euro's debilities sheds light not only on the euro's (in)capacity to rival the dollar as an international currency, but also on the future of both the euro and the dollar in the aftermath of the euro-zone crisis

The Nature of Financial and Real Business Cycles: The Great Moderation and Banking Sector Pro-Cyclicality

This paper takes a fresh look at the nature of financial and real business cycles in OECD countries using annual data series and shorter quarterly and monthly economic indicators. It first analyses the main characteristics of the cycle, including the length, amplitude, asymmetry and changes of these parameters during expansions and contractions. It then studies the degree of economic and financial cycle synchronisation between OECD countries but also of economic and financial variables within a given country, and gauges the extent to which cycle synchronisation changed over time. Finally, the paper provides some new evidence on the drivers of the great moderation and analyses the banking sector's pro-cyclicality by using aggregate and bank-level data. The main findings show that the amplitude of the real business cycle was becoming smaller during the great moderation, but asset price cycles were becoming more volatile. In part this was linked to developments in the banking sector which tended to accentuate pro-cyclical behaviour

Determinants of Carry Trades in Central and Eastern Europe

In this paper, I analyze determinants of carry trade returns in Central and Eastern Europe (CEE). I show that carry trades to CEE were lucrative due to interest rate spreads between the funding and investment currency from 2004 to 2006. They became unprofitable when liquidity risk and exchange rate volatility increased after 2007. The analysis suggests that the exchange rate regime of the CEE economy matters for carry trade returns. Overall, exchange rate stabilization, particularly via managed floats, seems to allow for the highest profit opportunities

Global Integration of Central and Eastern European Financial Markets: The Role of Economic Sentiments

This paper examines the importance of different economic sentiments, e.g. consumer moods, for the Central and Eastern European countries (CEECs) during the transition process. We first analyze the importance of economic confidence with respect to the CEEC's financial markets. Since the integration of formerly strongly regulated markets into global markets can also lead to an increase of the dependence of the CEECs' domestic market performance from global sentiments, we also investigate the relationship between global economic sentiments and domestic income and share prices. Finally, we test whether the impact of global sentiments and stock prices on domestic variables increases proportionally with the degree of integration. For these purposes, we apply a structural cointegrating VAR (CVAR) framework based upon a restricted autoregressive model which allows us to distinguish between the long-run and the short-run dynamics. For the long run we find evidence supporting relationships between sentiments, income and share prices in case of the Czech Republic. Our results for the short run suggest that economic sentiments in general are strongly influenced by share prices and income but also offer some predictive power with respect to the latter. What is more, global sentiments play an important role in particular for the CEECs' share prices and income. The significance of this link increases with economic integration
