On Lionel McKenzie's 1957 intrusion into 20th‐century demand theory

In this essay, we read McKenzie's 17 paragraphs of 1957 on “Demand Theory Without a Utility Index” as an opening to the narrative of 20th‐century demand theory and as a lever for the understanding of what has now reached culmination as the neoclassical theory of demand. In tracking the influence of these paragraphs on both theoretical and applied work, we also use them as a foothold for reflection on the process of theorizing to argue for the view that one cannot neglect the (changing) problematic that the theory is adduced to address, that the historical narrative behind a particular theorem is indispensable in understanding the theorem itself. This implicit theorizing of the process of theorizing then forces us to consider Stigler's distinction between textual and scientific exegesis and confront it to a second‐order level of theorizing, and thereby bring out the continuity, possibly not quite seamless, between a theorem and its history.     

External resources and economic growth: New evidence from EAGLE countries using PMG framework

This study attempts to explore the relationship between economic growth and external resources in the case of emerging and growth-leading economies (EAGLE). Among these economies, a panel of eight countries was studied over the period of 1986–2014. Empirical analyses were performed using panel cointegration and pooled mean group framework. Our findings support positive long- and short-run relationships between imports and gross domestic product (GDP). The results also reveal a negative and significant long-run relationship between foreign direct investment and GDP, whereas no significant evidence has been noted for the short run. Moreover, remittances in EAGLE countries have failed to justify any contribution to GDP in both long and short runs.     

PRIVATE INTERGENERATIONAL TRANSFERS AND THEIR ABILITY TO OFFSET THE FISCAL BURDEN OF AGEING

The ratio of retirees to workers in developed countries is expected to increase sharply in the next few decades. In the presence of unfunded income support policies, this increase in old age dependency is expected to increase the future fiscal burden of ageing, which is seen as a threat to living standards. Private intergenerational transfers in the form of bequests are also expected to increase in ageing societies, which may offset the adverse effects of the fiscal burden of population ageing on future living standards. This paper quantifies the ability of these private intergenerational transfers to offset the future fiscal burden of ageing in Australia. This is done through developing a dynamic overlapping generations simulation model with realistic demographics. Calculations based on steady-state simulations (with a pay-as-you-go tax rate equal to 3.3% of GDP) suggest that a bequest to GDP ratio of 1% offsets approximately one-third of the fiscal burden over the lifecycle when measured as a proportion of simple labour income and one-eleventh of the fiscal burden when measured as a proportion of full income (labour income plus leisure). The model is calibrated for Australia under a small open economy assumption such that the optimal solution mimics important cross-sectional and time-series fundamentals of the Australian economy. For the non-steady-state, intergenerational accounting suggests that the empirically plausible intergenerational transfers are strong enough to offset most of the tax burden (80–90%) when measured as a percentage of simple labour income and up to one-quarter of the burden when fiscal burden is measured as a percentage of full income.     

Economic status of households and labour supply to market and non-market activities mdash; some results from a poor rural economy

Assuming a given underlying utility structure for all households, we have demonstrated that the differential labour supply behaviour among household categories results owing to the different sets of constraints they face depending on their economic status and asset ownership. Using the criteria implied by the theoretical model four household gorups are defined. The labour supply functions estimated for these four groups support the theoretical result of significantly different supply behaviour. The empirical exercise, as expected, indicates that the labour supply decision of the subsistence group is guided by their need to achieve the minimum level of consumption while the middle-income households, who do not have enough non-labour income to meet their minimum subsistence need, tend to work longer hours in market activities than the workers from high-income households. However, market labour supply by high-income households is found to be relatively more sensitive to changes in the wage rate. The behaviour of the household groups differ so significantly that if an aggregate model is estimated ignoring inter-household differences, the predicted hours will grossly over-estimate labour supply to market activities.     

A Model of Sponsorship Effects on the Sponsor's Employees

Drawing from the corporate sponsorship literature, a model is developed that seeks to explain how externally directed corporate sponsorship can influence the behavior of the sponsor's employees. External sponsorship conveys a signal that can impact on employees’ perceptions of their employer. The model seeks to explain the processes and types of possible impacts. Although the model requires confirmation, its conceptualization raises additional avenues to assess the benefits of corporate sponsorship.     

Willingness to Pay for Pesticide Free Fruits: Evidence from Pakistan

ABSTRACT

This paper analyzes factors influencing consumption decision of pesticide free fruits (PFF) and estimates the willingness to pay (WTP) price premium for PFF in Pakistan. A contingent valuation survey of 200 households was conducted using face to face interview and payment card method. Results suggested that 93.5% respondents were WTP higher prices for PFF. Remarkably, around 35% respondents were WTP 16–20% higher prices and 24% respondents were WTP 6–10% higher prices for PFF than the existed conventional price. In addition, our ordered logit regression suggests that demographic and socio-economic variables such as age, education, income, household’s size and perception about health benefits are significantly associated with higher WTP for PFF.     

The Harris-Todaro hypothesis and the Heckscher-Ohlin-Samuelson trade model : A synthesis

We report a model of the Harris-Todaro variety in which capital is mobile and the urban wage is endogenous. Our model subsumes several other models presented in the literature. We extend the central theorems of trade to our model and also present formulae for the shadow wage and shadow rental. Our principal findings include (a) nonexistence of equilibrium in an important specialization of the model; (b) a factor-price and unemployment rate equalization theorem: and (c) an identical subsidy to labor but a differential subsidy to capital for obtaining a second-best optimum.     

Exact arbitrage, well-diversified portfolios and asset pricing in large markets

For a market with an atomless continuum of assets, we formulate the intuitive idea of a “well-diversified” portfolio, and present a notion of “exact arbitrage”, strictly weaker than the more conventional notion of “asymptotic arbitrage”, and necessary and sufficient for the validity of an APT pricing formula. Our formula involves “essential” risk, one based on a specific index portfolio constructed from factors and factor loadings that are endogenously extracted to satisfy an optimality property involving a finite number of factors. We illustrate how our results can be translated to markets with a large but finite number of assets.
