Exploration-exploitation tradeoffs and information-knowledge gaps in self-regulated learning: Implications for learner-controlled training and development

Learning in modern organizations often involves managing a tradeoff between exploration (i.e., knowledge expansion) and exploitation (i.e., knowledge refinement). In this paper, we consider the implications of this tradeoff in the context of learner-controlled training and development. We then propose a model that integrates research on control theory, curiosity, and skill acquisition to explain how information knowledge gaps (i.e., gaps between what learners believe they know and what they desire to know) guide resource allocation decisions throughout the learning process. Using this model, we present testable propositions regarding (a) the different approaches learners take when resolving exploration-exploitation tradeoffs, (b) how systematic changes in learner perceptions translate into changes in systematic learner behavior, and (c) how common biases in key learner perceptions can undermine the functioning of self-regulated learning in training and development contexts. We finish with a discussion of the model's implications for the science and practice of training and development.     

WAGE VOLATILITY AND CHANGING PATTERNS OF LABOR SUPPLY

Over the past few decades, the skilled–unskilled hours differential for U.S. men increased when the skill premium rose sharply, in contrast with dominant income effects. Based on PSID data, we show that over the 1967–2000 period, skilled men experienced a three times larger increase in wage volatility than unskilled men. With the rise in wage volatility, our general equilibrium incomplete markets model generates a 2.7 hours increase in the hours differential whereas it increased by 1.4 hours in the data. We find that hours adjustments are important for self‐insurance in the short run, whereas precautionary savings play a crucial role eventually.

Comparing Open-Ended Choice Experiments and Experimental Auctions: An Application to Golden Rice

We use two experimental valuation methods to estimate consumer demand for genetically modified golden rice. The first is an open-ended choice experiment (OECE) where participants name the quantities of golden rice and conventional rice demanded at each of several price combinations, one of which will be randomly chosen as binding. This allows us to estimate market demand by aggregating demand across participants. This estimate of market demand also allows us to estimate own-price elasticity and consumer surplus for golden rice. Comparing willingness-to-pay (WTP) estimates from the OECE with those from a uniform-price auction, we find that OECE WTP estimates exhibit less affiliation across rounds, and the effects of positive and negative information under the OECE are more consistent with prior expectations and existing studies. We also find that, while auction WTP estimates more than double across five rounds, OECE WTP estimates are stable across rounds and are always roughly equal to those from the final auction round.     

Corporate diversification and the value of individual firms: A Bayesian approach

Research summary: Prior theory suggests that the performance effects of a firm's diversification strategy depend on a firm's individual resources and capabilities and the setting within which it is operating. However, prior tests of this theory have examined the average diversification‐performance relationship across all firms, instead of estimating the diversification‐performance relationship at the individual firm level. Efforts to estimate this average relationship are inconsistent with a central assumption of much of strategic management theory—that firms maximize value by choosing strategies that exploit their heterogeneous resources and individual situation. By adopting an approach that allows an evaluation of the diversification‐performance relationship for individual firms, this article shows that firms, both focused and diversified, tend to choose that diversification strategy—focus, related diversification, or unrelated diversification—that maximizes value. Managerial summary: Instead of a universal diversification discount or premium, this article shows that the effect of diversification on performance is heterogeneously distributed across firms and that firms tend to be rational in their diversification decisions.

On becoming a strategic partner: The role of human resources in gaining competitive advantage

Although managers cite human resources as a firm's most important asset, many organizational decisions do not reflect this belief. This article uses the value, rareness, imitability, and organization (VRIO) framework to examine the role that the human resource (HR) function plays in developing a sustainable competitive advantage. Why some popularly cited sources of sustainable competitive advantage are not, and what aspects of a firm's human resources can provide a source of sustainable competitive advantage are discussed. The role of the HR executive as a strategic partner in developing and maintaining competitive advantage within the firm is also examined. © 1998 John Wiley & Sons, Inc.     

A social networks approach for strengthening participation in technology innovation: lessons learnt from the Mount Elgon region of Kenya and Uganda

Participatory approaches to agricultural technology development have not yet fully lived up to their promise to incorporate farmer knowledge. This paper introduces a social networks approach (SNA) to improve participatory research processes for co-innovation. Drawing upon findings from a collaborative project developing conservation agricultural production systems for smallholders in western Kenya and eastern Uganda, the paper explores farmer support networks to improve participation in technological innovation and development. Key research themes include: identifying farmers’ agricultural production networks; the local articulation of agricultural production networks and mindsets; using networks to facilitate meaningful participation in technology development; and disadvantages and advantages of using a social network approach. The introduction of SNA improved participatory research by building external and internal legitimacy for determining who participates, discouraging participatory attrition, and providing a meaningful forum for participation of all stakeholders. As a result, the introduction of SNA is demonstrated to show strong promise for improving processes of participatory technology development in agriculture.     

The economics of politically-connected firms

Political connections between firms and autocratic regimes are not secret and often even publicly displayed in many developing economies. We argue that tying a firm’s available rent to a regime’s survival acts as a credible commitment forcing entrepreneurs to support the government and to exert effort in its stabilization. In return, politically-connected firms get access to profitable markets and are exempted from the regime’s extortion. We show that such a gift exchange between government and politically-connected firms can only exist if certain institutional conditions are met. In particular, the stability of the regime has to be sufficiently low and the regime needs the power to exploit independent firms. We also show that building up a network of politically-connected firms acts as a substitute for investments in autonomous stability (such as spending on military and police force). The indirect strategy of stabilizing a regime via politically-connected firms gradually becomes inferior when a regime’s exploitative power rises.
