Using daily data for 34 emerging markets in the period 1994-2016, we find robust evidence that higher export commodity prices are associated with higher sovereign bond returns (indicating lower sovereign risk). The economic effect is especially pronounced for heavy commodity exporters. Examining the drivers, we find, first, that commodity-dependence is higher for countries that export large volumes of volatile commodities and that the effect increases in times of recessions, high inflation, and expansionary U.S. monetary policy. Second, the importance of raw material prices for sovereign financing can likely be mitigated if a country improves institutions and tax systems, attracts FDI inflows, invests in manufacturing, machinery and infrastructure, builds up reserve assets and opens capital and trade accounts. Third, the concentration of commodities within a country’s portfolio, its government indebtedness or amount of received development assistance appear to be only of secondary importance for commodity-dependence.

We propose a resolution of the missing deflation puzzle. Our resolution stresses the importance of nonlinearities in price- and wage-setting when the economy is exposed to large shocks. We show that a nonlinear macroeconomic model with real rigidities resolves the missing deflation puzzle, while a linearized version of the same underlying nonlinear model fails to do so. In addition, our nonlinear model reproduces the skewness of inflation and other macroeconomic variables observed in post-war U.S. data. All told, our results caution against the common practice of using linearized models to study inflation and output dynamics.

• The cyclical upswing of the world economy comes to an end, since expansionary policies in the US are expected to peter out in 2019, and the protectionist course of the US government clouds the perspectives for world trade. • However, if a major trade conflict can be avoided, chances are good that world production growth will be close to the long-run average of a bit more than 3%, with trade expanding at a similar pace. • Slowing exports, in particular to China, can partly explain the setback, while domestic conditions still appear favourable: firms continued hiring, albeit by less than before, tight labour markets in many member countries have caused wages to rise more quickly, and house prices continue to increase markedly. • Since a trend to higher inflationary dynamics is still not detectable, the ECB is likely to either keep key interest rates unchanged in 2019 or raise them very carefully at the end of the year. • All in all, we expect the euro area growth rate to come down from 1.9% in 2018 to 1.5% in 2019 and 1.8% in 2020, and inflation to slightly slow down from 1.8% in 2018 to 1.6% in 2019 and 1.5% in 2020.

Point estimates and error bands for SVARs that are set identified are only justified if the researcher is persuaded that some parameter values are a priori more plausible than others. When such prior information exists, traditional approaches can be generalized to allow for doubts about the identifying assumptions. We use information about both structural coefficients and impacts of shocks and propose a new asymmetric t-distribution for incorporating information about signs in a nondogmatic way. We apply these methods to a three-variable macroeconomic model and conclude that monetary policy shocks are not the major driver of output, inflation, or interest rates.

We introduce a novel currency risk measure based on American Depositary Receipts (ADRs). Using an augmented ADR pricing model, we exploit investors’ exposure to potential devaluation losses to derive an indicator of currency risk. Using weekly data for a sample of 807 ADRs located in 21 emerging markets over the 1994–2014 period, we find that a deterioration in the fiscal balance and higher inflation increase currency risk. Interaction models reveal that the fiscal balance and inflation drive the determination of currency risk for countries with poor sovereign rating, low foreign reserves, low capital account openness and managed float regimes.

• Signs of a slowing world economy are piling up: Since the beginning of the year purchasing manager indices have been declining globally, in summer higher US interest rates led investors to withdraw capital from emerging markets, and as a consequence, capital costs rose and currencies depreciated in many emerging markets economies. In October stock prices decreased markedly worldwide including the US, despite the strong upswing in this country. • As a consequence of the turmoil on financial markets, monetary conditions in many emerging economies are no longer favorable. What ultimately counts for the prospects of the global economy, is, however, the performance of the US, the Euro area, China and Japan. The upswing in the US appears stable enough to continue well into 2019. While at present the rest of the group appears to lose momentum, there is a good chance that production in each of these economies will still expand at rates that are close to their potential growth. Further protectionist rounds are the most important risk to this scenario. • In the first half of the current year the euro area economy expanded at a markedly slower rate than in 2017, about 0.4% per quarter, but still substantial. Rising risk premia on Italian assets will probably force banks in this large country to tighten credit conditions, and a slowing world trade will dent export growth. All in all, we expect GDP growth in the euro area to go down from 2.4% in 2017 to 2.0% in 2018 and to 1.7% in 2019. • Employment continues to expand and vacancy rates are at present higher than in 2017. As a consequence, wages rise more quickly: nominal compensations per employee started accelerating early in 2017, and negotiated wages followed at the beginning of 2018. Wage inflation of slightly below 2.5% and healthy growth in employment raise real labor incomes markedly. • Our forecasts are based on the assumption that rating agencies will continue as-signing investment grade to the Italian government debt, and that the Italian government and the European Commission will find a compromise about the draft budget of the country in the coming weeks. Another assumption is that the UK will not exit the EU in an unorderly way in March 2019.

Der Aufschwung in Deutschland geht in sein sechstes Jahr. Er hat allerdings an Fahrt eingebüßt. Dies hat sowohl nachfrageseitige als auch angebotsseitige Gründe. Zum einen hat sich das Auslandsgeschäft im Einklang mit der Verlangsamung der Konjunktur in den wichtigsten deutschen Absatzmärkten abgeschwächt. Zum anderen sehen sich Unternehmen allem Anschein nach zunehmend produktionsseitigen Engpässen gegenüber, vor allem bei Arbeitskräften und beim Bezug von Vorleistungsgütern. Überlagert wird dies durch Probleme in der Automobilindustrie im Zusammenhang mit der Einführung des neuen Prüfverfahrens WLTP, die aufgrund der hohen gesamtwirtschaftlichen Bedeutung der Branche sichtbare Spuren beim Zuwachs des Bruttoinlandsprodukts hinterlassen. Die Umstellungsprobleme dürften aber im Winterhalbjahr überwunden werden. Hinzu kommen Impulse aufgrund von finanzpolitischen Maßnahmen, die zum Jahresbeginn 2019 in Kraft treten. Im Durchschnitt dürfte die Wirtschaftsleistung nach einem Zuwachs um 1,7 Prozent in diesem Jahr mit Raten von 1,9 Prozent im Jahr 2019 und 1,8 Prozent im Jahr 2020 expandieren. Die Beschäftigung dürfte weiter spürbar, wenngleich mit abnehmendem Tempo ausgeweitet werden. Die registrierte Arbeitslosigkeit nähert sich gegen Ende des Prognosezeitraums wohl der Marke von 2 Millionen. Die Inflation wird sich dabei voraussichtlich von 1,8 Prozent im Durchschnitt dieses Jahres auf 2,0 Prozent im kommenden Jahr beschleunigen und 2020 bei 1,9 Prozent liegen. Trotz einer expansiv ausgerichteten Finanz-politik zeichnen sich für den Staat weiterhin Haushaltsüberschüsse ab, die allerdings von 54 Milliarden Euro auf 41 Milliarden Euro zurückgehen werden.

Since the global financial crisis, monetary economics new questions include the explanation and response to unusual consumer price developments but also the interdependencies between financial markets and real economic activity and its implication for the monetary policy transmission mechanism. This dissertation investigates these questions by presenting empirical evidence that accounts for non-linearities of the relevant economic relations. The first and second chapters examine inflation dynamics of the Euro area and ASEAN-5 economies using non-linear Phillips curve models. The results suggest that changes in inflation processes are mainly driven by the development of long-term inflation expectations. The third chapter investigates the evolution of the financial accelerator (FA) taking into account the developments of the financial sector. The results of a time-varying structural vector autoregressive model indicate that the FA effect for the USA has increased from the early 1990s.

• In summer 2018 the cyclical upswing of the world economy is not over, but it appears to be fragmenting. While economic activity in the European Union has lost steam, the upswing in the US has gained pace, and growth in China appears to be robust. • Markets for commodities as well as for capital are at present strongly affected by political movements: oil prices are more than 50% higher than one year ago, as the US exit from the Iran nuclear deal puts the long run oil supply from Iran at risk, and the strongly expansionary US tax reform explains the rise in US long run interest rates. . • Uncertainties about the future international trade system cause firms to slow down or even reverse the globalization of value chains. As an early consequence, world trade in the second half of 2018 and in 2019 will expand at much slower rates than during 2017. • In the euro area growth slowed in the first quarter 2018, due to weaker investment activity in France and Italy and, more importantly, a fall in exports in all larger euro area economies except Spain. However, the drivers of the upswing such as low interest rates for credit and expanding real incomes will still be supportive in the near future, and fiscal policies will be slighly more expansionary. But a slowdown in world trade will dent export growth as well as corporate profits. All in all, we expect GDP growth in the euro area to go down from 2.4% in 2017 to 2.1% in 2018 and to 1.7% in 2019 – a forecast that will only be realized if damages to the international trade system are limited and if the European sovereign debt crisis does not come back. • While wage inflation has been slowly increasing during the past quarters to about 2%, a clear upwards trend of core consumer price inflation is still not detectable. The recent jump of the headline rate to 1.9% is due to higher oil prices. Our forecasts for 2018 and 2019 are close, although still below, 2%.
