Exploring the widening food gap: an international perspective

Using data for a long panel of 90 developed and developing countries, this article explores the effects of research and development (R&D) and fixed capital stock on agricultural land productivity over the period 1961–2012. Instruments are used for R&D to deal with feedback effects and measurement errors. The results show very high social returns to investment in R&D and to fixed capital stock, suggesting that increasing investment in these factors are promising ways of arresting the increasing food prices due to increasing demand for animal protein, population growth, desertification, salinization, soil erosion, climate change, and decreasing growth in land productivity.     

Non‐Homothetic Multisector Growth Models

Multisector growth (MSG) models are dynamic versions of computable general equilibrium (CGE) models. Non‐homothetic preference (utility) functions are required for the evolution of factor allocations and industrial structures in accordance with consumption expenditure patterns implied by the non‐unitary income elasticities observed in all budget data since Engel in the 1850s. But comparative static general equilibrium solutions and particularly solving the dynamics of MSG models require explicit specifications of all demand and cost (price) functions. On the demand side, the constant differences of elasticity of substitution (CDES) non‐homothetic indirect utility functions and Roy's identity provide the explicit Marshallian demand functions and budget shares. Sectorial constant elasticity of substitution (CES) cost functions and Shephard's lemma provide the explicit relative commodity price functions and the sectorial cost shares and capital–labor ratios. Walrasian equilibria are given by one equation and the multisector dynamics by three differential equations. Benchmark solutions are given for three cost regimes of a 10‐sector MSG model. History patterns of industrial/allocational evolutions are recognized.     

Fiscal Institutions and Wage Bargaining in the Local Public Sector

In a theoretical analysis of the properties of different wage setting and financing systems in the local public sector, two financing systems are considered. A benchmark model with local financing through local taxes is compared with a system of centralized financing through grants, where taxes are decided at the national level. It is shown that the wage outcomes under centralized financing depend heavily on the order of moves in the budgetary game between the central and local levels.

Real Wages in Australia and Canada, 1870–1913: Globalization versus Productivity

Australia's and Canada's real wage experiences between 1870 and 1913 were distinctive. Faster productivity growth underpinned Canada's overtaking of Australia's wage levels. The globalization forces of migration and trade also shaped their comparative wages, principally by reducing wage growth in Canada. Immigration increased slightly Australia's real wages, but reduced wage levels in Canada, and tempered there the beneficial effects of rising productivity and improving terms of trade. In contrast, wage earners' share of national income rose after 1890 in Australia, with the productivity slowdown hitting chiefly rents and profits. Distributional shifts favouring wage earners in Australia, and the depressing effects of mass immigration on wages in Canada, limited Canada's wage lead before 1914, despite her faster productivity growth.     

Pitfalls in estimates of the relationship between stock returns and inflation

Empirical tests of the Fisher hypothesis give conflicting results, regardless of whether income growth is accommodated in the estimates. This paper shows theoretically and empirically that standard methods of testing the Fisher hypothesis give biased results and that the bias depends on the specification of the Fisher equation, the process governing inflation, measurement of inflation expectations, and the time aggregation of the data. Alternative tests show that share markets take several years to adjust to innovations in inflation and therefore that the Fisher hypothesis cannot be maintained.

The significance of sustained entrepreneurial orientation on performance of firms – A longitudinal analysis

This study focuses on the importance of changes in entrepreneurial orientation (EO) over time for subsequent firm performance, and the significance which inimitable resources (networks, governance system and unique competence) might have in this connection. Hypotheses are developed to test the effects that changes in EO level over a time period and resources have on subsequent firm performance. The study is based on data from 168 Norwegian SMEs, interviewed both in 2000 and 2003. The primary contribution of this study is that a change in EO over time (increased or decreased), may be of importance for a firm's performance represented by performance compared to competitors, and employment growth. A focus on entrepreneurial activities seems to be beneficial in the long run (increasing EO), while the opposite is the case if the EO level decreases. It is especially encouraging to see that firms focusing on EO (increased or the same) are positively associated with employment growth, one of the primary policy goals world-wide. Another contribution from this study is that resources that may be inimitable for firms have some influence on performance compared to competitors. Implications for policy-makers, practitioners and further research are discussed.     

Upper Secondary School Completion and the Business Cycle

Previous evidence suggests that enrollment in post‐compulsory education increases (decreases) in cyclical downturns (upturns). However, little evidence exists on whether enrollment is successfully transformed into completed education. This paper adds to the literature by analyzing the relationship between completion of upper secondary education and regional unemployment using Norwegian regional panel data on students graduating from compulsory school between 1981 and 2004. We find robust evidence that completion rates are countercyclical. Our results suggest that poor labor‐market conditions when starting upper secondary education have a lasting effect and motivate students to stay in school and graduate.
