What is going on in the oil market?

Conclusion In this article, we propose a consistent view on the recent oil-price history based on fundamental data and economic theory. We sum up: After the turn of the century three major stylized shocks have hit market. First, the demand curve has shifted fight outwards, mainly driven, as extensively reported in the media, by sustained growth in China and other Asian Countries. Second, supply disruptions in countries with low extraction costs (Iraq and Venezuela) have shifted the supply curve to the left. Third, we show that speculators adjust their inventories in order to take advantage of predictable price fluctuations and play themselves a major role in the price formation. Optimal storage theory implies that aggregate inventories are negatively related to the oil price and positively to the volatility of supply and demand shocks. We provide evidence that the political events in the last years have increased volatility and induced the inventory curve to shift right outwards. We analyze in a graphical framework the interaction of all these shocks and conclude that speculators have caused the oil price to overshoot in the short run its long-run fundamental value. However, this is not at all attributable to market failure or the harmfulness of speculators. In fact, the opposite is true. Speculators have in general a dampening effect on the oil price. The record oil price in the very recent history is partly a consequence of speculators maintaining or building-up inventories to cope with the supply and demand shocks to come. Hence, high prices represent a short-term toll for future price stability. It follows from our analysis that the oil price is expected to fall towards its long-term mean, provided that no further shocks hit the economy and, critically, the oil supply. As we saw, this prediction is consistent with the observed prices in the futures markets. Also in terms of future price volatility, the outlook is rather upbeat. The increased inventory levels held by speculators will cushion the spot market against fluctuations in natural supply and demand and limit the degree to which the currently high underlying volatility will translate into higher price volatility.

Investigating the PPP hypothesis using constructed U.S. dollar equilibrium exchange rate misalignments over the post-bretton woods period

This paper investigates the PPP-hypothesis over the post-Bretton Woods period using a representation of the equilibrium exchange rate (EER) that is an alternative to the real exchange rate. The results provide evidence in support of the relative-PPP hypothesis over the current period of floating exchange rates (1974–2005); while stronger evidence is found for the post-Plaza Accord period (1986–2005). EERs based on export price indexes (EPI) and constructed traded goods price indexes (TPI) best demonstrate the mean reverting behavior of the spot exchange rate as opposed to those EERs based on CPI, PPI, or the GDP-deflator. This mean reverting behavior is slightly improved if one takes international interest rate differentials into account; however EERs extended by productivity differentials do not indicate any improvements over the base model. Over the post-Plaza Accord period average half-lives of less than 1 year are reported using TPI-based EERs, adjusted by interest rate differentials. For large misalignments, we find probabilities that the spot exchange rate will converge towards the constructed CPI-based equilibrium exchange rate of up to 80%. Lastly, over the post-Plaza Accord period, the TPI-based EERs are able to statistically significantly outperform the pure random walk at short-term forecast horizons of less than 1 year for some spot exchange rates.     

External economic policy and development policy

Since 1970 the world economy has gone through a series of grave crises which have stimulated an intensive discussion about the economic and political relations between industrialized and developing countries. As seen from the Federal Republic of Germany, the witnessed events have not only an international dimension, but they focus attention again on one particular problem of national economic policy, the relationship of external economic policy and development policy, because the new strains on the international plane are in part reflected by this relationship.     

Globalisation, the global village and the civil society

Human dynamics, institutional change, political relations and the global environment have become increasingly intertwined. The development of multicultural societies has certainly not been without its problems. The re-emergence of extremist political parties, the segregation of cultures and ethnic conflict, illustrate the problematic side of socio-cultural integration at the local level. We argue that socio-cultural factors not only change as a result of globalisation, but also can be causes, as well as challenges to the process of globalisation itself. We describe how the recent introduction of the MGI and KOF globalisation indices can be used to empirically address to what extent globalisation affects social phenomena. Overall, while the rigidity of national boarders slackens, to speak about a global community is misleading. National borders still exist and the nation-state still matters. The fact is that they have to co-exist with civil society. The institutions of global civil society place limits upon the government and function as a sort of check on various forms of government, especially the authoritarian and absolutist varieties.     

For how long do IMF forecasts of world economic growth stay up-to-date?

This study analyses the performance of the International Monetary Fund (IMF) World Economic Outlook output forecasts for the world and for both the advanced economies and the emerging and developing economies. With a focus on the forecast for the current year and the next year, we examine the durability of IMF forecasts, looking at how much time has to pass so that IMF forecasts can be improved by using leading indicators with monthly updates. Using a real-time data set for GDP and for indicators, we find that some simple single-indicator forecasts on the basis of data that are available at higher frequency can significantly outperform the IMF forecasts as soon as the publication of the IMF’s Outlook is only a few months old. In particular, there is an obvious gain using leading indicators from January to March for the forecast of the current year.     

Development aid and international politics: Does membership on the UN Security Council influence World Bank decisions?

We investigate whether elected members of the UN Security Council receive favorable treatment from the World Bank, using panel data for 157 countries over the period 1970–2004. Our results indicate a robust positive relationship between temporary UN Security Council membership and the number of World Bank projects a country receives, even after accounting for economic and political factors, as well as regional, country and year effects. The size of World Bank loans, however, is not affected by UN Security Council membership.     

Does government ideology affect personal happiness? A test

We investigate the impact of government ideology on left-wing as compared to conservative individuals. We find that conservative people are happier, on average. In a sample excluding the richest countries left-wing people are happier under the tenure of left-wing governments.
