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.     

Comparing tests of the theory of exhaustible resources

The empirical relevance of Hotelling’s exhaustible resource theory has been tested with primarily negative results. Tests have been performed on various resources, at different levels of aggregation, with varying market structures, and over different time periods. Consequently, it is difficult to draw any general conclusions concerning the theory’s applicability in explaining producer behavior, given the assumptions and restrictions implicit in the data and tests. This paper compares test results when the implicit restrictions associated with the data are removed. Employing a single data set we compare the results for four published tests. Even with this uniform data set, two approaches reject the theory while two do not.     

Major transitions in ‘big’ history

‘Big’ history treats events between the Big Bang and contemporary technological life on Earth as a single narrative, suggesting that cosmological, biological and social processes can be treated similarly. An obvious trend in big history is the development of increasingly complex systems. This implies that the degree to which historical systems have deviated from thermodynamic equilibrium has increased over time. Recent theory suggests that step-wise changes in the work accomplished by a system can be explained using steady-state non-equilibrium thermodynamics. This paper argues that significant macro-historical events can therefore be characterized as transitions to steady states exhibiting persistently higher levels of thermodynamic disequilibrium which result in observably novel kinds or levels of organisation. Further, non-equilibrium thermodynamics suggests that such transitions should have particular temporal structures, beginning with sustainable energy innovations which result in novelties in organisation and in control mechanisms for maintaining the new organisation against energy fluctuations. We show how events in big history which qualify as historically significant by these criteria exhibit this internal structure. Big history thus obeys law-like processes, resulting in a common pattern of major transitions between steady-state historical regimes. This common process from cosmological to contemporary times makes big history a viable and relevant field of scientific study.     

A rigorous periodization of ‘big’ history

‘Big’ history is the time between the Big Bang and contemporary technological life on Earth. The stretch of big history can be considered as a series of developments in systems that manage ever-greater levels of energy flow, or thermodynamic disequilibrium. Recent theory suggests that step-wise changes in the work accomplished by a system can be explained using steady-state non-equilibrium thermodynamics. Major transitions in big history can therefore be rigorously defined as transitions between non-equilibrium thermodynamic steady-states (or NESSTs). The time between NESSTs represents a historical period, while larger categories of time can be identified by empirically discovering breaks in the rate of change in processes underlying macrohistorical trends among qualities of NESSTs. Two levels of periodization can be identified through this procedure. First, there are two major eons: cosmological and terrestrial, which exhibit qualitatively different kinds of historical scaling laws with respect to NESST duration and the gaps between NESSTs: the first eon decelerating, the second accelerating. Accelerating rates of historical change are achieved during the Terrestrial Eon by the invention of information inheritance processes. Second, eras can also be defined within Earth history by differences in the scaling of energy flow improvement per NESST. This is because each era is based on a different kind of energy source: the material era depends on nuclear fusion, the biological era on metabolism, the cultural era on tools, and the technological era on machines. Periodizing big history allows historians to uncover the mechanisms which trigger the innovations and novel organisations that spur thermodynamic transitions, as well as the mechanisms which keep historical processes under control.     

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 Path to Full Employment? ‘They're Dreamin'!’

This short article critically reviews Mitchell and Watts's Buffer Stock Employer (BSE) model proposal. It concludes that the BSE scheme is unlikely to reduce the long-run unemployment rate.     

An empirical, small scale ‘Traded–Nontraded Goods’ model for New Zealand

In this paper, an empirical model of the traded–nontraded goods model was built in order to examine the effect of various policy variables on the real exchange rate and resulting impacts on the variation in industrial supply, demand and employment levels. This framework was also built to search and simulate alternative policy settings to 1984 economic reforms of New Zealand, that would possibly decrease the short-term adjustment costs of 1984 reforms. It was found that, particularly the output contraction and employment loss in exportable industries, would have been lower if the liberalization in the exportable and importable industries had followed similar timing.     

Some problems in modelling the optimal division of a ‘cake’ between an unknown number of participants

The trade-off between the survival time of a fixed population and its consumption rates, when resources are exhaustible, has been studied by Koopmans. A link is established between this model and the traditional neoclassical literature on optimum population. The model is embedded in a larger model in which limited control over population growth rates is feasible, but in which the initial population size acts as a constraint on development. The optimal depletion rate of the exhaustible resource and optimal survival times are then explored. This facilitates a sensitivity analysis of the optimal policy and a discussion of the robustness of the results of Koopmans.     

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.’     

Trade and Diversity: Is There a Case for ‘Cultural Protectionism?’

Abstract. In contrast to the predictions of standard models of international trade, globalization critics are claiming that trade destroys diversity. We demonstrate that with endogenous sunk costs, trade integration in horizontally differentiated industries can indeed lead to a fall in diversity. Consumers are faced with a tradeoff between gains in real income and a loss in diversity, so that the impact on welfare is ambiguous. However, it is possible through fiscal policies to replicate pre-trade choices and still realize gains in real income. Thus, calls for a 'cultural protectionism' are not justified.     

Using justice principles to resolve the ‘Impossibility of a Paretian Liberal’

A simple, but general, possibility result is presented showing how ‘justice’ principles can be effectively used to resolve Amartya Sen's ‘The Impossibility of a Paretian Liberal’ (1970a).
