Constructing migration: Infrastructure,poverty and development in KwaZulu‐Natal

Migration and population movement are probably the most neglected of the significant dynamics behind rural poverty in South Africa. Little is known about how people move from place to place, and much of what we thought we knew may be incorrect. In KwaZulu‐Natal job search is no longer the single dominating reason given for migration. Instead, infrastructure ties with it for first place today, with land close behind. The first article in this two‐part report notes that as many as two thirds of the province's disadvantaged families have broken away from their communities of origin and moved at least once during their lifetimes. Perhaps three million have migrated in the last fifteen years. A second unexpected finding is the predominance of rural‐to‐rural migration. Three quarters of all moves recorded were rural to rural, with many orientated towards advantaged rural areas around small towns and secondary cities. Results show how streams are channelled towards poverty or opportunity, and argue for a review of prevailing concepts of rural‐urban relations which structure delivery efforts. The second article, to follow later, notes that recorded income levels are now higher in some rural destination areas than in the urban shack communities that accommodate rural‐to‐urban migrants. Results of various studies presented show how access to information affects migration patterns, and the article also explores the role of infrastructure as a determining force in the regional distribution of population and as a factor in people's own bootstrap anti‐poverty efforts.     

Governing cooperation hazards of outsourced municipal low contractibility transactions: An exploratory configuration approach

Increasingly, public sector organizations (PSOs) outsource the delivering of important welfare services. This gives rise to important questions of how PSOs can control their suppliers. The purpose of this paper is to show how PSOs manage cooperation hazards of low contractibility transactions, i.e., activities expected to be difficult to govern. The paper applies a taxonomic configuration approach which means we apply a holistic view on the governance of suppliers and search for internally congruent governance packages that also are adapted to the context of the transactions. We find indications of the importance of internal congruence in governance packages in order to effectively deal with cooperation hazards. We also notice that the intensity in and types of controls in inter-organizational relationships are affected by the amount of cooperation hazards. A conflict between a relational and a bureaucracy-based governance package in one of the configurations is argued to be the main driver behind lower expectations about positive behaviour from suppliers.     

Risk‐taking channel of monetary policy

One of the most robust stylized facts in macroeconomics is the forecasting power of the term spread for future real activity. We propose a possible causal mechanism for the forecasting power of the term spread, deriving from the balance sheet management of financial intermediaries and the “risk‐taking channel of monetary policy.” Monetary tightening leads to the flattening of the term spread, reducing net interest margin and credit supply. We provide empirical support for the risk‐taking channel.     

Trust over time in exchange relationships: Meta‐analysis and theory

A common premise in prior research is that trust increases over time in relationships. Through a meta‐analysis of 39 studies, we find that the bivariate correlation between trust and relationship duration (1) is on average positive and small, and (2) varies significantly across studies indicating the presence of unobserved moderators. We therefore build a theoretical framework to specify four different mechanisms—initial bias correction, change in relationship value, identification, and trust‐based selection—that may affect the development of trust. We then argue that the relative strength of these mechanisms should influence whether trust increases, remains constant, or decreases over time. © 2013 The Authors.

How to approach business model innovation: the role of opportunities in times of (no) exogenous change

Firms need to show dynamic adaptability and innovate their business models to achieve survival and growth, in particular when they are exposed to high levels of exogenous change. However, business model innovation also takes place in the absence of exogenous change. We know relatively little about firms’ approaches to opportunities for business model innovation in both of these environmental settings. The objective of this study is to understand how firms exposed to various environmental conditions explore and exploit business model innovation opportunities. In a qualitative multiple case analysis, the study compares the approaches to business model innovation used by four firms exposed to high levels of exogenous change with those of four firms operating in the absence of exogenous change. The findings are contrasted with entrepreneurial opportunity discovery and creation theories. The results reveal that firms exposed to high levels of exogenous change focus on discovering objective opportunities, whereas firms operating in the absence of exogenous change concentrate on creating opportunities for business model innovation. However, this study revealed that when the firms further explore and exploit these opportunities, they tend to combine the behaviours that the two opportunity perspectives suggest. This study contributes to the literature on business model innovation by emphasising the relationship between environmental context and approach to business model innovation and by reinforcing the link with entrepreneurship theory.     

Managerial Political Behavior in Innovation Portfolio Management: A Sensegiving and Sensebreaking Process

By applying formalized innovation portfolio management systems, firms seek to ensure an alignment of their goals and strategy with their employees' different abilities, actions, and outcomes. However, research indicates that nonrational, political behavior also determines formalized innovation portfolio management decision‐making processes. Research on political behavior in respect of innovation portfolio management usually conceptualizes political behavior as a set of self‐serving activities, such as negotiation, bargaining, coalition building, and acquiring power, aimed at protecting, maintaining, or promoting an actor's self‐interest and power. Consequently, extant research tends to focus on political behavior's dysfunctional impacts on decision‐making processes and their subsequent outcomes. This paper challenges this negativity bias by exploring a novel, neutral specification of political behavior and its relation to innovation portfolio management decision‐making processes. By conducting an automotive industry case study focusing on the innovation portfolio management decision‐making processes, the paper analyzed the data from 43 interviewees. The conceptual model shows that managers' political capabilities determine their ability to behave politically. According to the results, political behavior comprises the activities that prepare the stage and orchestrate others in order to form a political coalition. Furthermore, results show that political behavior functions as a sensegiving and a sensebreaking process, with managers seeking to shape an innovation project's understanding according to their interests and to influence portfolio decisions. The resulting novel specification of political behavior extends the construct's scope and validity by investigating their functional and dysfunctional aspects, and by indicating that a political sensemaking process complements formalized innovation portfolio management decision‐making processes.     

Minimum return guarantees,investment caps,and investment flexibility

We study the merits of capped retirement products with guarantee for investors who have the flexibility to dynamically adjust their investment strategy. All contracts under consideration are fairly priced such that the net profit of the provider is zero. Without the rider, an expected utility maximizing CRRA investor does not want an investment cap. Here, she commits herself to a strategy a priori. With the flexibility rider, the optimization problem changes and the optimal strategy is a response to an exogenously set price. A fair pricing then anticipates the optimal response of the investor. We show that the maximum expected utility of the investor can, for anticipated fairly priced products, be obtained for a finite cap. Thus, a capped product design can give a Pareto improvement to the otherwise uncapped contract version.     

Carry

We apply the concept of carry, which has been studied almost exclusively in currency markets, to any asset. A security’s expected return is decomposed into its “carry,” an ex-ante and model-free characteristic, and its expected price appreciation. Carry predicts returns cross-sectionally and in time series for a host of different asset classes, including global equities, global bonds, commodities, US Treasuries, credit, and options. Carry is not explained by known predictors of returns from these asset classes, and it captures many of these predictors, providing a unifying framework for return predictability. We reject a generalized version of Uncovered Interest Parity and the Expectations Hypothesis in favor of models with varying risk premia, in which carry strategies are commonly exposed to global recession, liquidity, and volatility risks, though none fully explains carry’s premium.
