The knowledge production of ‘R’ and ‘D’

Many studies investigate the relationship between R&D and patents applying knowledge production functions. Using aggregated R&D may underestimate the productivity of ‘R’, as mainly ‘R’ but not ‘D’ leads to patents. Disaggregating ‘R’ and ‘D’ shows a significant premium of ‘R’ towards patenting.     

Global Investment Environment of the Post‐Quantitative Easing World: The ‘new‐old’ and ‘new‐new’ Normal

Global markets since late 2007 are not ‘normal’, where normal means market conditions we would expect to observe going forward in the absence of any new economic shocks. Financial markets have been dominated by extraordinary central bank policies that were created to deal with challenging market conditions reflecting heightened risk aversion and illiquidity. Markets in the future will have some characteristics that look more like the market conditions observed in the pre‐crisis period, which I call the ‘new‐old normal’ and other conditions that differ from the past, which I call the ‘new‐new normal’. I first review what happened during the financial crisis in terms of developments in three asset classes, equities, fixed income and currencies, to place the forward‐looking view in proper context. Then the transition period from the quantitative easing (QE) era of exceptional monetary policy to post‐QE markets is discussed. Post‐transition, we will see some features of the post‐QE world that will resemble pre‐crisis market conditions, the ‘new‐old normal’ with higher policy interest rates, wider cross‐country interest differentials, lower cross‐asset return correlations and a resurgence of the importance of cross‐country differences in fundamentals in international investing. However, some features of the post‐QE investment environment will be unlike anything observed in the past: the ‘new‐new normal’ with reduced liquidity and more days of exceptionally large volatility and asset price moves due to regulatory effects resulting in a reduced ability of market‐makers to provide inventory buffers for counterparties and electronic trading venues that shut down trading in high volatility periods; low inflation; flatter yield curves; and emerging markets providing less opportunity for diversification gains as they converge to developed financial market characteristics.     

‘Us’ and ‘Them’: the origin of identity,and its economic implications

Abstract We investigate the origins of identity and the innate proclivity to draw a distinction between ‘insiders’ and ‘outsiders’. We propose an evolutionary explanation: we argue that identity arises because it facilitates survival. In an evolutionary setting we endogenize preferences and demonstrate that the evolutionarily stable preferences fashioned by natural selection would distinguish between insiders and outsiders. We then work out the implications of such preferences in two contemporary scenarios, one entailing rent‐seeking behaviour and the other involving public good provision. Our results are in conformity with empirical evidence.     

A Dynamic Analysis of Licensing: The ‘‘Boomerang'’ Effect and Grant‐Back Clauses*

This article develops an incomplete contract model of the licensing relationship to analyze the dynamic effects of licensing on R&D competition in the innovation market and to examine the rationale for often observed ‘‘grant‐back'’ clauses. Of particular concern are how the consideration of future competition distorts the licensing relationship and how the grant‐back clause can mitigate this distortion. I also evaluate the validity of the casual antitrust argument that grant‐back clauses may adversely affect competition because they reduce the licensee's incentive to engage in R&D and thereby limit rivalry in innovation markets.     

Envelope and sensitivity analysis ‘in the large’

New results on global sensitivity analysis are derived. Relying on the saddle-point characterization of the Lagrangean, simple yet powerful results are shown to hold under general conditions. A generalized envelope result is obtained. It does not require differentiability assumptions or unique solution, and it holds for discrete changes.     

The ‘New Federalism’ and Horizontal Equalization*

Under Stage I of Australia's ‘New Federalism’ policy a given share of Commonwealth tax revenue is to be distributed to the States. This paper examines the States (Personal Income Tax Sharing) Act 1976 and proposes a concrete fiscal equalization criterion consistent with the provisions for equalization in the Act. Distribution models proposed in Mathews (1979) and Commonwealth Grants Commission (1981) are examined and shown not to satisfy this criterion. An alternative is presented.     

The ‘Troubling Tradeoffs’ Paradox and a Resolution

Ravallion ( 2012a ) argues that the Human Development Index (HDI) embeds questionable tradeoffs between the dimensions used to compute the index. To alleviate these problems he proposes the adoption of one of the indices developed by Chakravarty ( 2003 ). In this paper I identify the following paradox: while the Chakravarty indices clearly exhibit more sensible tradeoffs than the HDI, the HDI produces more sensible rankings than the Chakravarty indices. To solve the paradox I identify the axioms behind each methodology responsible for the unintuitive tradeoffs and rankings and illustrate how to develop an index with these questionable axioms removed. This approach can result in methodologies that exhibit more intuitive tradeoffs by design, as it seeks inputs from the public as to what those tradeoffs ought to be, and produces rankings that are more in line with what the HDI wishes to measure: human development and capabilities, as conceptualized by Sen ( 1985 ).     

Comments on ‘The state of macroeconomic forecasting’

The paper by Fildes and Stekler provides an overview of empirical results in macroeconomic forecasting. They do not address three key issues: (1) the importance of data revisions and the use of real-time data; (2) the statistical significance of differences between forecasts; and (3) the role of macroeconomic theory in formulating and evaluating macroeconomic forecasts.     

Entry Threats and Inefficiency in ‘Efficient Bargaining’

We study limit pricing in a model of entry with asymmetric information, where the incumbent firm's wage is endogenously determined through ‘efficient bargaining’ with its union. In the presence of entry threat, the incumbent firm‐union pair may face a conflict between rent sharing and transmitting its cost information. When the wage is not observable to outsiders and employment is the only signalling instrument, over‐employment features in all entry deterring contracts. When the wage is also observable, information transmission becomes easier. Most of the time, then, but not always, the efficient contract deters (induces) entry against the low (high) cost incumbent.     

Redistribution,state trading enterprises and ‘politically optimal’ tariffs

State trading enterprises (STEs) are widely used and can be viewed as instruments of trade policy. We analyse two aspects: the first is their potential trade distorting effect; the second is how they modify the case for the ‘politically optimal’ tariff. We show that the STE can reduce the need for a tariff designed for domestic redistribution. This result introduces some ambiguity about how STEs are interpreted: from a multilateralist perspective, they should be dealt with in the same way as other non‐tariff barriers; from a nationalistic perspective, they can reduce the need for ‘politically optimal.’     

Monetary integration in the ex‐Soviet Union: A ‘union of four’?*

The governments of four ex‐Soviet countries recently discussed forming a currency union. To examine the economic feasibility of this proposition, we use conventional techniques and show that the arrangement is likely to find it difficult to handle the lack of structural symmetry, the asymmetric pattern of shocks, and the lack of market flexibility among the potential participants. Moreover, the union would be a unilateral one. It would require an unusual degree of political commitment to survive. Nonetheless, there are some subtleties in the timing and pattern of mutual dependence between Russia and Kazakhstan, and to a lesser extent in Belarus, which may reduce the strain from a currency union in those countries. Otherwise, the black market will have to provide the necessary market flexibility.     

The brain drain, ‘educated unemployment’, human capital formation,and economic betterment1

Extending both the ‘harmful brain drain’ literature and the ‘beneficial brain gain’ literature, this paper analyzes both the negative and the positive impact of migration by skilled individuals in a unified framework. The paper extends the received literature on the ‘harmful brain drain’ by showing that in the short run, international migration can result in ‘educated unemployment’ and overeducation in developing countries, as well as a brain drain from these countries. A simulation suggests that the costs of ‘educated unemployment’ and overeducation can amount to significant losses for the individuals concerned, who may constitute a substantial proportion of the educated individuals. Adopting a dynamic framework, it is then shown that due to the positive externality effect of the prevailing, economy‐wide endowment of human capital on the formation of human capital, a relaxation in migration policy in both the current period and the preceding period can facilitate ‘take‐off’ of a developing country in the current period. Thus, it is suggested that while the migration of some educated individuals may reduce the social welfare of those who stay behind in the short run, it improves it in the long run.     

‘Beautiful Serbia’ ‐ objective and subjective outcomes of active labour market policy in a transition economy

This paper studies the causal impact of participation in the Beautiful Serbia programme providing training and temporary work in the construction sector in Serbia on labour market outcomes as well as on measures of subjective well‐being approximating individual welfare. According to our estimates, the positive impact of this particular programme appears much stronger when judged by subjective well‐being than when judged by the immediate labour market effect.     

Estimating the optimal hedge ratio in the presence of potential unknown structural breaks

We propose a new approach in the estimation of the optimal hedge ratio that allows the hedge ratio to vary over time but without the necessity of frequently rebalancing the portfolio. We apply this in the context of the US and UK equity markets using weekly spot share prices and future share prices during the period 5 January 1999 to 29 September 2009. Our method is to test for cointegration in the presence of two potentially unknown structural breaks by determining the timing of each via the underlying data. The empirical findings reveal that the spot and future prices are strongly cointegrated in each market. The estimated parameters disclose that the optimal hedge ratio is not constant in case of the US and the UK. We find one negative and one positive shift in the optimal hedge ratio in the US. However, we find only one significant and positive shift in the optimal hedge ratio in the UK. The implication of these findings from the perspective of both investors as well as policy-makers is elaborated on in the main text.     

Comments on : ‘The decline and rise of political economy’, by Bruce Yandle

The first part of the argument is a reformulation of Yandle's problem and a sketch of the current apologetics of Public Choice Theory and its pitfalls. In the second part it is argued that Yandle's thesis on the connection between the social value of political economy and the size of the state displays identical flaws. An improved specification is needed to save this challenging thesis.
