Im JEP sind nun Beiträge aus zwei Symposien über die Entwicklung der Einkommen der reichsten 1% bzw. die Situation des Euroraums erschienen.

Die auf der Seite verlinkten Aufsätze bieten viel und guten Lesestoff.

"The top 1 percent income share has more than doubled in the United States over the last 30 years, drawing much public attention in recent years. While other English-speaking countries have also experienced sharp increases in the top 1 percent income share, many high-income countries such as Japan, France, or Germany have seen much less increase in top income shares. Hence, the explanation cannot rely solely on forces common to advanced countries, such as the impact of new technologies and globalization on the supply and demand for skills. Moreover, the explanations have to accommodate the falls in top income shares earlier in the twentieth century experienced in virtually all high-income countries. We highlight four main factors. The first is the impact of tax policy, which has varied over time and differs across countries. Top tax rates have moved in the opposite direction from top income shares. The effects of top rate cuts can operate in conjunction with other mechanisms. The second factor is a richer view of the labor market, where we contrast the standard supply-side model with one where pay is determined by bargaining and the reactions to top rate cuts may lead simply to a redistribution of surplus. Indeed, top rate cuts may lead managerial energies to be diverted to increasing their remuneration at the expense of enterprise growth and employment. The third factor is capital income. Overall, private wealth (relative to income) has followed a U-shaped path over time, particularly in Europe, where inherited wealth is, in Europe if not in the United States, making a return. The fourth, little investigated, element is the correlation between earned income and capital income, which has substantially increased in recent decades in the United States."
"Imagine a society with perfect economic equality. Then, one day, this egalitarian utopia is disturbed by an entrepreneur with an idea for a new product. Think of the entrepreneur as Steve Jobs as he develops the iPod, J. K. Rowling as she writes her Harry Potter books, or Steven Spielberg as he directs his blockbuster movies. The new product makes the entrepreneur much richer than everyone else. How should the entrepreneurial disturbance in this formerly egalitarian outcome alter public policy? Should public policy remain the same, because the situation was initially acceptable and the entrepreneur improved it for everyone? Or should government policymakers deplore the resulting inequality and use their powers to tax and transfer to spread the gains more equally? In my view, this thought experiment captures, in an extreme and stylized way, what has happened to US society over the past several decades. Since the 1970s, average incomes have grown, but the growth has not been uniform across the income distribution. The incomes at the top, especially in the top 1 percent, have grown much faster than average. These high earners have made significant economic contributions, but they have also reaped large gains. The question for public policy is what, if anything, to do about it."
"The eurozone currently confronts severe short-run macroeconomic adjustment problems and a deficient institutional architecture that has to be reformed in the longer run. Europe's efforts at economic and monetary union are historically unprecedented. However, the gold standard provides lessons regarding what will and won't work, macroeconomically and politically, in the short run, while US history provides long-run lessons regarding appropriate institutional structures. The latter also suggests that institutional reform only happens at times of great crisis, and that it cannot be taken for granted. The eurozone's leaders may therefore ultimately have to take heed of the lessons of history regarding currency union breakups."
"Since the onset of the Great Recession in peripheral Europe, nominal hourly wages have not fallen from the high levels they had reached during the boom years -- this in spite of widespread increases in unemployment. This observation evokes a well-known narrative in which nominal downward wage rigidity is at the center of the current unemployment problem. We embed downward nominal wage rigidity into a small open economy with tradable and nontradable goods and a fixed exchange-rate regime. In this model, negative external shocks cause involuntary unemployment. We analyze a number of national and supranational policy options for alleviating the unemployment problem caused by the combination of downward nominal wage rigidity and a fixed exchange-rate regime. We argue that, in spite of the existence of a battery of domestic policies that could be effective in solving the unemployment problem, it is unlikely that a solution will come from within national borders. This leaves supranational monetary stimulus as the most compelling avenue out of the crisis. Our model predicts that full employment in peripheral Europe could be restored by raising the euro area annual rate of inflation to about 4 percent for the next five years."
