On the dynamics of profit-led and wage-led growth

This paper examines how variable output and profit share jointlydetermine investment and saving, while the difference betweeninvestment and saving drives the changes in output and profitshare. Analysis of the resulting pair of differential equationsyields novel implications for the multiplier process. In thismore general framework a number of separate strands of the Keynesian-inspiredliterature can be understood. In particular, the model incorporatesboth forced saving and profit squeeze to analyse the stabilityof the dynamical system, and brings out the complex relationbetween in and out-of-equilibrium profit-led and wage-led regimes.     

Cross-border production sharing and exchange-rate sensitivity of Mexico's trade balance

Increasing patterns of international trade occur in the form of cross-border production sharing – the dispersion of separate blocks of an integrated production process across different nations. In the case of ‘standard’ or ‘ordinary’ trade, imports are destined for use in the importing country, and exports are largely produced within the country. However, with production sharing, imported parts and components are destined for inclusion in the country's exports. A depreciation of a nation's currency raises its exports. At the same time, imported components become more expensive, which partly offsets the expansionary effect of the depreciation on exports. Using a simple theoretical framework, this paper shows that production networks lower the sensitivity of a country's trade balance to changes in exchange rates. The empirical examination finds Mexico's Maquiladora trade balance to be unresponsive to changes in both, its real effective as well as its real peso-dollar rates, while that for non-Maquiladora category is significantly responsive, in confirmation with the theorized hypothesis.     

R&D and Technological Learning in Indian Industry: Econometric Estimation of the Research Production Function

Estimation of research production functions has produced rich and useful results for developed countries in the past. This paper makes a pioneering attempt to estimate the same in the context of a less-developed country (LDC) (India). The objective is to examine the process of technology generation and learning in Indian industry. The existing literature recognizes two principal characteristics of technological activities in LDCs. First, their R&D effort is geared towards "minor" as opposed to "major" innovations. Second, technological learning constitutes an integral part of their research thrust. This paper attempts to capture these characteristics in a rigorous econometric framework by estimating a comprehensive research production function incorporating the role of learning. We use Indian firm-level in-house R&D data for two sectors: pharmaceuticals and electronics. Our study not only captures the role of learning in determining research effort and research output, but also re-examines some of the existing hypotheses relating to the effects of firm size, technology import and ownership. We find that the two sectors display two distinct learning trajectories, but in both cases learning proves to be crucially important in technology generation.     

Adapting to succeed? Leveraging the brand equity of best sellers to succeed at the box office

Many movies are based on best-selling novels. While book adaptation is an often used strategy in the motion picture industry, it has received little academic attention. Using a multi-method approach, this research investigates the drivers behind the success of book-based movies. In Study 1, we analyze over 700 movies and find that book-based movies perform better at the box office on the opening weekend than non-book movies. However, this superior performance dissipates after the opening weekend. Further, the opening weekend performance of book-based movies is positively driven by book equity, book-movie similarity, and recency between the book??s peak equity and movie release. After the opening weekend, many of these book-related variables cease to have an impact, and the effect of movie-related variables (e.g., reviews) increases. Because Study 1 documents that book-movie similarity positively impacts the movie??s performance, contrary to prior findings that content similarity has negative or null impact on performance of a movie sequel, we undertake a second study to reconcile the discrepancy. Study 2 finds that content similarity results in satiation and therefore hampers the movie success for sequels; however, when a movie is adapted from a book, due to experiential modality change (i.e., from book format to film format rather than film to film), content similarity increases the movie??s chance of success.     

What Do We Know about Trade Promotions? Contributions,Limitations, and Further Research

The trade promotion area remains seriously under-researched compared with its share of the overall marketing mix budget. This review attempts to provide an up-to-date account of what we know about trade promotions. For eight major topics we elaborate on what that topic means in the context of trade promotions, why it has been deemed important, what empirical findings have emerged in that area, and proposeareas for future research.     

Indian economy and Indian private equity

India's gross domestic product has been growing at more than 8% in the past few years, making it the fourth‐largest economy in terms of purchasing power parity. According to a Goldman Sachs report, India could become the second‐largest economy in the world by 2050. The key growth drivers are investments in infrastructure, domestic consumption, and a hub for global outsourcing. This is further supported by growth‐oriented policies by the government. The favorable environment has led to the growth of the private equity market. India received approximately U.S. $17.5 billion of investments in private equity in 2007, making it the number‐one destination in Asia. Indian private equity has been mainly focused on providing growth/expansion capital to the company as compared to buyouts in the developed markets. © 2008 ICICI Bank Limited.

Idiosyncratic Risk Matters!

This paper takes a new look at the predictability of stock market returns with risk measures. We find a significant positive relation between average stock variance (largely idiosyncratic) and the return on the market. In contrast, the variance of the market has no forecasting power for the market return. These relations persist after we control for macroeconomic variables known to forecast the stock market. The evidence is consistent with models of time‐varying risk premia based on background risk and investor heterogeneity. Alternatively, our findings can be justified by the option value of equity in the capital structure of the firms.     

Stability and Largeness of the Core

In general, there are examples of TU games where the core is stable but is not large. In this paper, we show that the extendability condition introduced by Kikuta and Shapley (1986, “Core Stability in n-Person Games,” Mimeo) is sufficient for the core to be stable as well as large, for TU games with five or fewer players. We provide a counter example when the number of players is six. We then introduce a stronger extendability condition and show that it is necessary and sufficient for the core to be large. Our proof makes use of a well-known result from the theory of convex sets. Journal of Economic Literature Classification Number: C71.
