Biofuels technology development in Southern Africa

ABSTRACT

The benefits of biofuels depend on the feedstock, conversion pathway and local context. This paper assesses biofuels technology readiness and developments to provide foresight to biofuels development in Southern Africa. Efficient conversion pathways, coupled with biomass from waste or high-yielding energy crops, will reduce both the costs of biofuels production, and the environmental impacts. Compared to petroleum fuels, the current commercial biofuels (ethanol, biogas and biodiesel) typically offer carbon emission reductions of 30–50% but are marginally more expensive. The extent of biofuels market penetration will therefore be influenced by mandates (blending targets) and subsidies (green premium). Advanced biofuels promise greater efficiencies and carbon emission reductions at reduced cost but will require further research and development to reach commercialisation. If developed appropriately, biofuels can reduce carbon emissions and improve energy security, while enabling sustainable agriculture and improved natural resources management.     

Pandemic (COVID‐19) Policy,Regional Cooperation and the Emerging Global Production Network†

In this paper, we explore the possible policy responses to the COVID‐19 pandemic shock as well as the related economic (financial crisis) shocks on trade and global value chains (GVC) in East Asia. We find that regional policy coordination is critical to mitigate and isolate the pandemic shock. It is important to identify the pandemic events early to flatten the pandemic curve at the national and regional level. This supports a recent study by the World Bank (2020), which highlights the importance of early mitigation policies during the pandemic shock. The cost of the pandemic and economic shocks will increase significantly when several countries in the region experience the pandemic shock concurrently. In this case, flattening the regional pandemic curve becomes important. The results also indicate the need for greater coordination in East Asia to mitigate the pending economic shock in terms of unemployment, corporate bankruptcy and financial market fragility. The paper also highlights that the stability of the GVC network is critical during the pandemic in terms of hedging the risk of disruptions to the procurement of critical medical and health products as well as maintaining service linkages to manufacturing, such as the logistics sector. Regional policy coordination and the stability of GVC will be valuable in the post‐pandemic recovery of the region.     

Prepurchase financing pool: Revealing the IRR problem

Internal rate of return (IRR) is one of the most common and important indicators in investment analysis because it is often used by managers and practitioners as a decision-making criterion. Moreover, the IRR reflects the financial cost in financing decisions and it helps to answer the following question when comparing different financing alternatives: “Which loan is the cheapest?” Among the different types of loans in Brazil, there is a financial product called a prepurchase financing pool (PPFP) that is generally regarded as the best option for financing or loans. The objective of this article is to use the prepurchase financing pool to show the flaws of IRR in financial analysis. In particular, when IRR is used to evaluate the prepurchase financing pool, one finds problems of reliability regarding (i) existence, (ii) uniqueness, and (iii) economic interpretation of the rate. The results show that the prepurchase financing pool is relevant evidence that the IRR flaws are found in financial products.     

Exploring the Role of Product Development Capability for Transforming Marketing Intelligence into Firm Performance

ABSTRACT

Purpose: This study examines the role of product development capability for transforming marketing intelligence activities into firm performance on industrial markets.

Methodology/Approach: The authors apply structural equation modeling to analyze survey data from 342 industrial manufacturing companies.

Findings: Results reveal that sales integration and holistic macroeconomic view are particularly important features of the marketing intelligence capability on industrial markets to gain additional insights in order to develop products successfully. Results also reveal that product development capability transforms the marketing intelligence activities into firm performance on industrial markets.

Research Implications: This study offers new insights on marketing theory by extending and concretizing the concept of market orientation to a broader concept of the marketing intelligence capability for industrial markets. Further, this research reveals that the product development capability serves as a mediator to business performance.

Practical Implications: This study’s systematic and tangible outline of the dimensions of marketing intelligence and its link to the product development capability helps firms to better understand how to capitalize on market orientation’s potential values.

Originality/Value/Contribution: This research (a) reveals the relevant dimensions of marketing intelligence on industrial markets and (b) shows how the product development capability tranforms marketing intelligence activities into firm performance on industrial markets.     

Building from Scratch: New Cities,Privatized Urbanism and the Spatial Restructuring of Johannesburg after Apartheid

By the start of the twenty‐first century, the once dominant historical downtown core of Johannesburg had lost its privileged status as the center of business and commercial activities, the metropolitan landscape having been restructured into an assemblage of sprawling, rival edge cities. Real estate developers have recently unveiled ambitious plans to build two completely new cities from scratch: Waterfall City and Lanseria Airport City (formerly called Cradle City) are master‐planned, holistically designed ‘satellite cities’ built on vacant land. While incorporating features found in earlier city‐building efforts, these two new self‐contained, privately‐managed cities operate outside the administrative reach of public authority and thus exemplify the global trend toward privatized urbanism. Waterfall City, located on land that has been owned by the same extended family for nearly 100 years, is spearheaded by a single corporate entity. Lanseria Airport City/Cradle City is a planned ‘aerotropolis’ surrounding the existing Lanseria airport at the northwest corner of the Johannesburg metropole. These two new private cities differ from earlier large‐scale urban projects because everything from basic infrastructure (including utilities, sewerage, and the installation and maintenance of roadways), landscaping, security services, the regulation of common spaces, and selling and branding the city are firmly in the hands of private profit‐making corporate entities and outside the mandate of public authorities.     

Operational performance of U.S. public rail transit and implications for public policy

In today's tough economic environment, governments at all levels face significant budget shortfalls and public rail transit systems must compete with other public services for government subsidies. It is critical that public rail transit systems be concerned with their operational performance and efficient use of resources. In this paper, we develop a methodology that measures a rail transit system's performance relative to that of other rail transit systems, compares its performance to an appropriate efficient benchmark system, and identifies the sources of its inefficiency. We analyze the relationship between public subsidies and operational performance of public rail systems and show an inverse relationship between subsidization and efficiency.     

Optimizing service-level and relevant cost for a stochastic multi-item cyclic production system

A multi-item make-to-order production system in a stochastic environment is analyzed. Assuming a common cycle production approach, the impact of safety stock, cycle time, demand, processing time and setup time on service-level and total relevant cost (holding, setup and backorder cost) is determined. To illustrate this relationship a trajectory for the service-level with respect to the relevant cost (holding and setup) is presented. Furthermore algorithms to calculate the cycle time which leads to maximum service-level at constant safety stock and to calculate the pair cycle time and safety stock which minimize total relevant cost are introduced.     

When do thick venture capital markets foster innovation? An evolutionary analysis

In this paper, we examine the trade off between different effects of the availability of venture capital on the speed of technological progress in an industry. We consider an evolutionary industry simulation model based on Nelson and Winter (1982), in which R&D efforts of an incumbent firm generate technological know-how embodied in key R&D employees, who might use this know-how to found a spinoff of the incumbent. Venture capital is needed to finance a spinoff, so that the expected profits from founding a spinoff depend on how easily venture capital can be acquired. Accordingly, thick venture capital markets might have two opposing effects. First, incentives of firms to invest in R&D might be reduced and, second, if spinoff formation results in technological spillovers between the parent firm and the spinoffs, the generation of spinoff firms might positively influence the future efficiency of the incumbent’s innovation efforts. We study the manner in which this tradeoff influences the effect of venture capital on innovation expenditures, speed of technological change and evolution of industry concentration in several scenarios with different industry characteristics.
