New Keynesian Phillips Curve and inflation dynamics in Australia

The New Keynesian Phillips Curve (NKPC) was developed as a response to the New Classical critique that Keynesian macroeconomics lacked micro-foundations. The NKPC provides theoretical micro-foundations that attempt to explain, inter alia, nominal rigidities and, explicitly price stickiness. This paper investigates the validity of the NKPC for Australia. In contrast to the findings for the USA and Euro area, we find that neither the output gap nor marginal cost appears to be a key driving force variable across different set of instruments and estimators (GMM and 2SLS) over the sample period from 1959 to 2009. The flattening of the NKPC along with significant presence of price stickiness is also found in the data. In particular, the reduced form coefficients and implied estimates from the structural parameters of the model support the view that inflation dynamics are forward looking while the role of lagged inflation is also statistically important only after 1980s. However, we claim that the forward looking baseline NKPC contrary to the hybrid NKPC is stable and better explains inflation dynamics for the Australian economy.     

On the strength of intellectual property protection that nations provide

Researchers studying the commitment of countries to intellectual property rights run into the claim that the technology-haves (the developed countries) opt for relatively stronger protection of intellectual property, whereas the technology-have-nots (the developing countries) opt for weaker protection. It is but a short step from this assertion to the claim that this results in huge trade losses for the former. Using cross-national panel data for 1981–2000 we find that the evidence is only weakly consistent with this conjecture at best; and that the technology-have-nots more likely provided weaker protection due to paucity of financial resources and human capital, and their inward-looking trade-orientation.     

Global slack hypothesis: evidence from China,India and Pakistan

It is widely believed that globalization has changed inflation process. The global resource capacity reduces responsiveness of inflation to domestic activity and increases responsiveness of inflation to global resource capacity. This global slack hypothesis is tested using different theoretical specifications, which also relate domestic output elasticity and foreign output elasticity to the degree of trade openness of an individual economy. The results reject this hypothesis. The global resource capacity does not drive domestic inflation. The impact of globalization has not increased in the inflation process, and the results yield important policy implications for monetary policy formulation. The global resource capacity does not affect ability of the central banks to stabilize inflation, real economic activity and also respond to the volatility of output growth.     

The Innovation‐R&D Nexus in an Emerging Economy: Evidence from the Indian Manufacturing Sector

While R&D is considered an important input for innovation, its relationship with the output of the innovation process continues to remain enigmatic, especially in developing countries with low levels of domestic research. Using patents and knowledge capital stock as proxies for the output and input of the innovation process, we study their nexus in the emerging economy of India using a large sample of manufacturing firms over the period 2001–2010. Using a specification that addresses the problem of ‘excess zeroes’ in count data, the firm's non‐technical knowledge stock as an additional factor of the success with which R&D transforms into patents, and a linear feedback mechanism that yields consistent estimators, we find that a one unit increase in knowledge capital likely raises expected patent count by only about 4.3% at most. Further, although patenting experience, resource access and knowledge spillovers are strongly significant in explaining patent counts, the magnitude of these effects is marginal at best. In brief, evidence for the knowledge production function is rather weak even in the context of a dynamic developing economy.     

Seasonality and Wage Responsiveness in a Developing Agrarian Economy

This paper studies the wage responsiveness of labour supply and demand, simultaneously addressing the twin issues of the non-clearing of developing rural labour markets and seasonality. It employs a data set pertaining to south-central India, and limits itself to the agricultural market for daily-rated labour (by far the predominant form of wage contract in the sample villages). Estimating a theoretically robust and empirically justified disequilibrium model of the agricultural labour market, we find no evidence of backward-bending supply curves or 'vertical' demand curves, contrary to findings in the literature. Further, while the agricultural labour market appears to be in equilibrium during the kharif (or rainy) season, it manifests excess supply in the rabi (or post-rainy) season.     

Does intellectual property protection spur technological change?

Of the diverse factors motivating technological change, onefactor that has received increasing attention in the recentpast has been the protection of intellectual property rights.Given fairly recent changes in the international policy ethoswhere a regime of stronger intellectual property protectionhas become a fait accompli for most developing countries (andthe developed too), it is of some significance to ask whethermore stringent protection of intellectual property does indeedencourage innovation. And this is the question which this paperexamines, utilising cross-country panel data on R&D investment,patent protection and other country-specific characteristicsspanning the period 1981–95. The evidence unambiguouslyindicates the significance of intellectual property rights asincentives for spurring innovation.
