Knowledge that Transforms

We investigate political determinants of land reform implementation in the Indian state of West Bengal. Using a village panel spanning 1974–1998, we do not find evidence supporting the hypothesis that land reforms were positively and monotonically related to control of local governments by a Left Front coalition vis-à-vis the right-centrist Congress party, combined with lack of commitment to policy platforms. Instead, the evidence is consistent with a quasi-Downsian theory stressing the role of opportunism (reelection concerns) and electoral competition.

Time Preference, Noncognitive Skills and Well Being across the Life Course: Do Noncognitive Skills Encourage Healthy Behavior? by Ngina Chiteji. Published in volume 100, issue 2, pages 200-204 of American Economic Review, May 2010

This paper analyzes an emissions trading program that was introduced to reduce smog-causing pollution from large stationary sources. Using variation in state level electricity industry restructuring activity, I identify the effect of economic regulation on pollution permit market outcomes. There are two main findings. First, deregulated plants in restructured electricity markets were less likely to adopt more capital intensive environmental compliance options as compared to regulated or publicly owned plants. Second, as a consequence of heterogeneity in electricity market regulations, a larger share of the permitted pollution is being emitted in states where air quality problems tend to be more severe.

This paper uses international trade data to examine the effects of climate shocks on economic activity. At the aggregate level, Melissa Dell, Benjamin F. Jones, and Benjamin A. Olken (2008) (hereafter, DJO) have demonstrated that higher temperatures in a given year reduce the growth rate of GDP per capita, but only in poor countries. The analysis of trade data in this paper builds on that finding, with three principal motivations. First, international trade links the fortunes of countries, providing potentially important conduits for geographically limited climatic impacts to have global economic effects. Second, international trade data is the best available source for identifying economic activity worldwide separately by narrowly defined sectors. Examining international trade data, one can thus say more precisely what sectors are affected by climatic changes. Finally, the trade data, collected by the importing country, provides a check on the potentially low-quality national accounts data provided by the home country.

We report experiments on sender-receiver games with an incentive for senders to exaggerate. Subjects “overcommunicate”—messages are more informative of the true state than they should be, in equilibrium. Eyetracking shows that senders look at payoffs in a way that is consistent with a level-k model. A combination of sender messages and lookup patterns predicts the true state about twice as often as predicted by equilibrium. Using these measures to infer the state would enable receiver subjects to hypothetically earn 16–21 percent more than they actually do, an economic value of 60 percent of the maximum increment.

What determines the term structure of interest rates? Standard economic theory links the interest rate for maturity T to the willingness of a representative agent to substitute consumption between times 0 and T. The standard model contrasts sharply with a more informal view based on investors ’ preferred habitat, proposed by John Culbertson (1957) and Franco Modigliani and Richard Sutch (1966). According to the preferred-habitat view, there are investor clienteles with preferences for specific maturities, and the interest rate for a given maturity is influenced by the demand of the corresponding clientele and the supply of bonds with that maturity. For example, the typical clientele for long-term bonds are pension funds. An increase in their demand would be expected to raise prices of long-term bonds and thus lower long-term interest rates. In short, preferred habitat implies that there is price pressure in the bond market. While the preferred-habitat view has intuitive appeal, it has not entered into the academic mainstream, typically being relegated to a paragraph in MBA-level textbooks. One reason for this is the mixed findings in early empirical studies of the term structure. Specifically, between 1962 and 1964, the US Treasury and Federal Reserve raised the supply of short-term government debt while simultaneously lowering the supply of long-term debt. This program, known as Operation Twist, aimed to raise short-term interest rates, and so improve the balance of payments, while also lowering long-term rates to stimulate private investment. A number of papers evaluated Operation Twist, and while they reached different conclusions, none found

into physical capital in a number of countries. However, the gains are found to be quite small.

A sender may communicate with a decision maker through intermediaries. In this model, an objective sender and intermediary pass on information truthfully, while biased ones favor a particular agenda but also have reputational concerns. I show that the biased sender and the biased intermediary's reporting truthfulness are strategic complements. The biased sender is less likely to use an intermediary than an objective sender if his reputational concerns are low, but more likely to do so if his reputational concerns are moderate. Moreover, the biased sender may be more likely to use an intermediary perceived to be more biased.

The past decade has seen the explosive emergence of online advertising as a major source of revenue for Internet publishers. Analyses of this phenomenon are mostly conducted in the sway of Google’s hugely successful search advertising program. In the early days of the Internet, before Google, virtually all advertising revenues were related to simple display ads. Yet by 2008 search advertising accounted for over $10.5 billion of the $23.4 billion in total online advertising, and pundits were forecasting continued growth at rates of 12 % per year over the next five years.1 Internet advertising markets have broken sharply from the advertising markets for traditional media. In the older media, every consumer that received a particular magazine, listened to a particular radio program, or watched a particular TV show would read, hear or see the same advertisement. An advertiser that wanted to reach an audience with particular characteristics could do so only within narrow limits. For example, a beer company might advertise on televised football games and a maker of fashion clothing might advertise in women's magazines. Although publications do some tailoring of their offerings, as when a newspaper has different local editions, audience mix is nevertheless

The real value of the US dollar has fluctuated widely during the global financial crisis and its aftermath. Beginning in early 2008 through early 2009, the dollar strengthened against most currencies but weakened considerably in the intervening months. We propose a decomposi tion of the forces driving the real exchange rate into a long run real interest rate component and a residual risk premium component. If real interest rates in the United States rise rela tive to its partners, the value of the dollar should strengthen. Likewise, if the level risk premium on foreign interest-bearing assets rises, the dol lar should also strengthen. We find that little of the recent movements in the dollar are directly attributable to the real interest component, sug gesting that most of the movements are due to the residual risk premium component. There is a large and diverse literature that affords a role to real interest differentials and to risk premiums in determining the real value of a currency. Our approach is almost purely definitional. The only assumptions we rely on are those of stationarity?of the real exchange rate and the US-foreign real interest differen tial. Specifically, let qt denote the log of the real exchange rate, defined as the foreign con sumer price level (converted into dollar terms
