This paper quantitatively assesses the effects of inflation shocks on the public debt-to-GDP ratio in 19 advanced economies using simulation and estimation approaches. The simulations based on the debt dynamics equation and estimations of impulse responses by local projections both suggest that a 1 percentage point shock to the inflation rate reduces the debt-to-GDP ratio by about 0.5 to 1 percentage points. The results also suggest that the impact is larger and more persistent when the debt maturity is longer, but the difference from the benchmark case is not significant. These results imply that modestly higher inflation, even if accompanied by some financial repression, could reduce the public debt burden only marginally in many advanced economies.

The paper studies the extent of global inflation synchronization using a dynamic factor model in a large set of countries over a half century. The authors' methodology allows them to account for differences across groups of countries (advanced economies and emerging market and developing economies) and to analyze commonalities in inflation synchronization across a wide range of inflation measures. The paper reports three major results. First, inflation movements have become increasingly synchronized internationally over time: a common global factor has accounted for about 22 percent of variation in national inflation rates since 2001. Second, inflation synchronization has also become more broad-based: while it was previously much more pronounced among advanced economies than among emerging market and developing economies, it has become substantial in both groups over the past two decades. In addition, inflation synchronization has become significant across all inflation measures since 2001, whereas it was previously prominent only for inflation measures that included mostly tradable goods.

Frequently, factors other than structural developments in technology and production efficiency drive changes in labor productivity in advanced and emerging market and developing economies (EMDEs). This paper uses a new method to extract technology shocks that excludes these influences, resulting in lasting improvements in labor productivity. The same methodology in turn is used to identify a stylized example of the effects of a demand shock on productivity. Technology innovations are accompanied by higher and more rapidly increasing rates of investment in EMDEs relative to advanced economies, suggesting that positive technological developments are often capital-embodied in the former economies. Employment falls in both advanced economies and EMDEs following positive technology developments, with the effect smaller but more persistent in EMDEs. Uncorrelated technological developments across economies suggest that global synchronization of labor productivity growth is due to cyclical (demand) influences. Demand drivers of labor productivity are found to have highly persistent effects in EMDEs and some advanced economies. Unlike technology shocks, however, demand shocks influence labor productivity only through the capital deepening channel, particularly in economies with low capacity for counter-cyclical fiscal policy. Overall, non-technological factors accounted for most of the fall in labor productivity growth during 2007-08 and around one-third of the longer-term productivity decline after the global financial crisis.

The causes and consequences of foreign direct investment (FDI) in developing countries remains a subject of debate among researchers and policymakers alike. The authors use international data and a new micro-data set of firms in thirteen Southern African Developing Countries (SADCs) to investigate the benefits and determinants of FDI in this region. FDI appears to have facilitated local development in the SADC region. Foreign firms tend to perform better than domestic firms, tend to be larger, are located in richer and better-governed countries and in countries with more competitive financial intermediaries, and they are more likely to export than domestic firms. They also exhibit positive spillover effects to domestic firms. Relying on a standard model to predict the country-level FDI inflows per capita, the authors find that SADC is attracting their expected level of FDI inflows, at least relative to its income level, human capital, demographic structure, institutions, and economic track record. There are some differences between SADC and the rest of the world in FDI behavior: in SADC, the income level is less important and openness more so. The authors use two comparison groups to compare with SADC to shed light on why other regions have attracted more FDI per capita than SADC. The factors that explain SADC's low FDI inflows are economic fundamentals (e.g., previous growth rates, average income, phone density, and the adult share of population).

A study of distortions to agricultural incentives in 18 developing countries during 1960-84, by Krueger, Schiff and Valdes (1988; 1991), found that policies in most of those developing countries were directly or indirectly harming their farmers. Since the mid-1980s there has been a substantial amount of policy reform and opening up of many developing countries, and indicators of that progress have been made available recently by a new study that has compiled estimates for a much larger sample of developing countries and for as many years as possible since 1955. The new study also covers Europe's transition economies and comparable estimates for high-income countries, thereby covering more than 90 percent of world agricultural output and employment. This paper summarizes the methodology used in the new study (pointing out similarities and differences with those used by the OECD and by Krueger, Schiff and Valdes), compares a synopsis of the indicators from Krueger, Schiff and Valdes and the new study for the period to 1984, summarizes the changing extent of price distortions across countries and commodities globally since then, and concludes by evaluating the degree of distortion reduction over the years since 1984 compared with how much still remains, according to the results of a global economy wide model.
