Learning to Build a Supply Network: An Exploration of Dynamic Business Models

abstract    Firms are confronted with the challenge of learning how to develop and manage supply networks, which reduce their operating costs and maximize their effectiveness in the marketplace. In pursuit of such goals they are increasingly turning to the use of dynamic business models. Dynamic business models represent continuous change and therefore make firms learn constantly new and better ways of doing things. These changes are manifestations of inter-firm knowledge transfer. The aim of this research is to explore dynamic business models as an example of inter-firm knowledge transfer. Adopting a case study approach, we examine three components of dynamic business models – network structure, inter-firm routines and knowledge forms – and describe their integration through a problem solving approach to building an offshore supply network. Our empirical findings suggest that dynamic business models help organizations identify and link key actors with each other (at the firm and individual level), and aid the identification and specification of appropriate knowledge types and knowledge transfer mechanisms for different actors, in different contexts.     

What (really) accounts for the fall in hours after a technology shock?

The paper asks how state of the art DSGE models that account for the conditional response of hours following a positive neutral technology shock compare in a marginal likelihood race. To that end we construct and estimate several competing small-scale DSGE models that extend the standard real business cycle model. In particular, we identify from the literature six different hypotheses that generate the empirically observed decline in hours worked after a positive technology shock. These models alternatively exhibit (i) sticky prices; (ii) firm entry and exit with time to build; (iii) habit in consumption and costly adjustment of investment; (iv) persistence in the permanent technology shocks; (v) labor market friction with procyclical hiring costs; and (vi) Leontief production function with labor-saving technology shocks. In terms of model posterior probabilities, impulse responses, and autocorrelations, the model favored is the one that exhibits habit formation in consumption and investment adjustment costs. A robustness test shows that the sticky price model becomes as competitive as the habit formation and costly adjustment of investment model when sticky wages are included.     

Analysing the impact of restructuring transportation,production and distribution on costs and environment – a case from the Thai Rubber industry

Transportation and distribution are key elements to successful supply chains, however there is some disagreement regarding the impact of distribution and transportation restructuring on costs and the environment. This paper explores the use of an optimisation model of Thailand’s rubber industry supply chain, to assess the impact of distribution and transportation on costs and greenhouse gas emissions. It has previously been observed that there is a positive correlation between transportation cost reduction and environmental impact, nevertheless the correlation is not clearly established when the distribution system is restructured. This paper is divided into two parts: the first part examines the impact of transportation service capacity on distribution decisions; the second part of the paper aims to examine the impact of restructuring the distribution network considering multi-modal options on cost and greenhouse gas emissions. For both parts a scenario analysis is utilised in conjunction with an optimisation model to derive the best possible answer in terms of costs and GHG emissions. In this paper, the results obtained indicate that the impact on cost minimisation from the increase in rail freight service capacity is marginal, while the impact on GHG emission minimisation is more significant. In terms of short-sea shipping prices and service capacity, the scenario analysis shows a slight positive impact on cost minimisation but no positive or negative impact on GHG emission minimisation. Results also confirm that in terms of economic advantages, distribution network restructuring provides greater benefit to the industry than does capacity development for the transportation service.     

长尾市场网络销售商的订单履行渠道选择模型

研究传统市场和长尾市场条件下,网络零售商保有库存策略和直运策略的选择模型。建立了单周期动态仿真模型,进行了算例仿真,测算了市场竞争、供应商折扣、零售商订购策略和消费者对网络销售方式的接受程度等影响因素对网络零售商总利润的影响。结果表明,在缺乏定价权的实际条件下,网络零售商要获得更高的销售利润,需要增加产品品类、争取更大的价格折扣、采购合适数量的产品、选择合适的订单履行渠道。在未来的长尾市场中,产品品类更多、竞争更激烈、消费者选择产品的视野更开阔,直运方式将代替保有库存方式成为许多网络零售商的主流订单履行方式。

The Importance of Attributes in Entrepreneurial Opportunity Evaluations: An Emerging Market Study

Although prior research has established that entrepreneurs have idiosyncratic perceptions about opportunity attributes, we do not yet understand the level of importances attached to attributes when evaluating opportunities. This article uses conjoint analysis to assess how trade‐offs are decided when evaluating opportunities considering both individual and business criteria. We hypothesize differences in the perceived importances of opportunities and the unique constellations therein. The results indicate that there is a significant difference in the degree of importance attached to the business sector, capital intensity, technology maturity, market potential and return on investment potential, when individuals evaluate an entrepreneurial opportunity. The business sector was identified as the principal determinant of opportunity attractiveness, followed closely by the market growth rate, which reflects emerging market conditions. By contextualizing the findings, it is suggested that emerging economies impose higher bureaucratic burdens on entrepreneurs, increasing uncertainty as well as operational and transactions costs of firms; therefore, reducing the incentive to invest in capital or technology.
