Informal economy, wage goods and accumulation under structural adjustment theoretical reflections based on the Tanzanian experience

Economic development in sub-Saharan Africa under structuraladjustment witnessed the upsurge of informal sector development—thedevelopment of unregulated labour-intensive activities, in partexport-oriented. This paper argues that two factors played animportant role in shaping the dynamics of informal sector development:(1) the process of the relative cheapening of wage goods asa result of their importation, partly financed through foreignaid, thereby lowering unit-labour costs in labour-intensiveproduction, and (2) the processes at work of subsidising realwages by other forms of economic security as a result of multiple,diversified and spatially extended livelihood strategies. Whilethese factors undoubtedly brought a new vitality to economicdevelopment, this paper questions the long-run sustainabilityof this new trend for two reasons. One is its dependence onforeign aid to finance imports. The other is that it does notappear to propel endogenous increases in productivity by achievinggreater synergy in intersectoral linkages between agricultureand industry.     

Dynamic order submission strategies with competition between a dealer market and a crossing network

We analyze a dynamic microstructure model in which a dealer market (DM) and a crossing network (CN) interact for three informational settings. A key result is that coexistence of trading systems generates systematic patterns in order flow, which depend on the degree of transparency. Further, we study overall welfare, measured by the gains from trade of all agents, and compare it with the maximum overall welfare. The discrepancy between both measures is attributable to two inefficiencies. Due to these inefficiencies, introducing a CN next to a DM, as well as increasing the transparency level, not necessarily produces greater overall welfare.     

IS THE CAPITAL STRUCTURE LOGIC OF CORPORATE FINANCE APPLICABLE TO INSURERS? REVIEW AND ANALYSIS

Since the financial crisis of 2008, next to banks, insurers have received increasing attention from researchers and regulators because of their crucial role in the financial system. A key point for a stable insurer is its capital structure, i.e. the choice between equity, debt and provisions in financing its operations. Based on earlier work a quickly developing literature has directly applied capital structure theories (in particular trade-off and pecking order) from corporate finance to insurers’ financing choices. Corporate finance concepts used herein however, are developed for industrial firms. In this paper we provide an overview of the literature on the capital structure of insurers, but contribute by systematically clarifying how to account for the specificities of insurers when transferring the trade-off and pecking-order logic from an industrial to an insurer context. This way, we add several new insights on an insurer's choice between equity, financial debt and provisions. In particular, we are able to explain why, as compared to industrial firms, insurers use less financial debt, and why insurers focus so strongly on self-financing. Finally, we identify multiple avenues for future research.     

Cost efficiency in the European securities settlement and depository industry

We examine whether the European settlement and custody institutions operate in an efficient way. To do this, we start from an analytically founded discussion regarding the activities performed by the operators in this sector. Based on the insights obtained, we estimate both a translog cost function and a constant elasticity of substitution – quadratic cost function. From the results obtained, there clearly are economies of scale in this industry. Moreover, also economies of scope between the activities performed are present. These findings imply that probably further consolidation is ahead, and that separating certain activities from others can only be done at a cost in terms of efficiency.     

Extra-role behavior in buyer–supplier relationships

This study develops theory and provides empirical evidence regarding the antecedents and consequences of extra-role behavior in supply relationships (i.e., supplier behaviors that go beyond formal role definitions and responsibilities and are oriented toward helping the buyer firm, referred to as partner ERB). Communal motivations, instrumental motivations, and role formalization explain the variation in partner ERB. Further, the effect of partner ERB on relationship profitability is contingent on the buyer partner's qualifications and the degree of technological unpredictability. An empirical test is presented based on 223 buyer–supplier relationships. Partner ERB has several drivers including role formalization. While partner ERB generally increases buyer profitability, in certain cases (e.g., for poorly chosen suppliers in a predictable environment) it may actually decrease it.     

Aggressive Orders and the Resiliency of a Limit Order Market

We analyze the resiliency of a pure limit order market by investigating the limit order book (bid and ask prices, spreads, depth and duration), order flow and transaction prices in a window of best limit updates and transactions around aggressive orders (orders that move prices). We find strong persistence in the submission of aggressive orders. Aggressive orders take place when spreads and depths are relatively low, and they induce bid and ask prices to be persistently different after the shock. Depth and spread remain also higher than just before the order, but do return to their initial level within 20 best limit updates after the shock. Relative to the sample average, depths stay around their mean before and after aggressive orders, whereas spreads return to their mean after about twenty best limit updates. The initial price impact of the aggressive order is partly reversed in the subsequent transactions. However, the aggressive order produces a long-term effect as prices show a tendency to return slowly to the price of the aggressive order.We thank Theo Nijman, Erik Theissen, Rob van den Goorbergh, Josef Zechner (editor) and an anonymous referee for valuable comments on an earlier draft as well as seminar participants at the EEA-conference in Venice, the CFS Conference on Market Design in Eltville, CORE, Leuven and Tilburg.

Planning for Agricultural Change and Economic Transformation in Tanzania?

Recently, Tanzania witnessed a revival of economic planning that explicitly aimed to combine rapid economic growth with accelerated structural transformation of the economy. To achieve these planning targets would require a relatively modest drop in the share of agriculture in GDP, but a dramatic fall in its share in employment by 2025. Tanzanian planners assume that labour is locked in agriculture because agricultural productivity is low, from which they conclude that, to release labour to fuel the expansion of manufacturing, it is imperative to raise agricultural productivity by appropriate land policies, leveraging private investment and developing public–private partnerships. We argue that, analytically, this planning argument leaves out the possibility that causality may run the other way – from high labour retention in agriculture to low agricultural productivity – and that, empirically, the observed patterns inherent in actual processes of economic transformation in Tanzania do not tally well with the assumptions of planners. More specifically, in so far as labour flows out of agriculture, it flows towards informal‐sector activities, both rural and urban, rather than towards formal manufacturing.     

The performance implications of outsourcing customer support to service providers in emerging versus established economies

Recent discussions in the business press query the contribution of customer-support outsourcing to firm performance. Despite the controversy surrounding its performance implications, customer-support outsourcing is still on the rise, especially to emerging markets. Against this backdrop, we study under which conditions customer-support outsourcing to providers from emerging versus established economies is more versus less successful. Our performance measure is the stock-market reaction around the outsourcing announcement date. While the stock market reacts, on average, more favorably when customer-support is outsourced to providers located in emerging markets as opposed to established economies, approximately 50% of the outsourcing firms in our sample experience negative abnormal returns. We find that the shareholder-value implications of customer-support outsourcing to emerging versus established economies are contingent on the nature of the customer support that is being outsourced and on the nature of the outsourcing firm. Customer-support outsourcing to emerging markets is less beneficial for services that are characterized by personal customer contact and high knowledge embeddedness than for customer-support services that involve impersonal customer contact and are low on knowledge embeddedness. Firms higher in marketing resource intensity and larger firms benefit more from outsourcing customer-support services to emerging markets than firms lower in marketing resource intensity and smaller firms.     

The impact of aggressive orders in an order-driven market: a simulation approach

This article investigates resiliency in an order-driven market. On basis of a vector autoregressive model capturing various dimensions of liquidity and their interactions, I simulate the effect of a large liquidity shock, measured by a very aggressive market order. I show that, despite the absence of market makers, the market is resilient. All dimensions of liquidity (spread, depth at the best prices and order book imbalances) revert to their steady-state values within 15 orders after the shock. For prices, a long run effect is found. Furthermore, different dimensions of liquidity interact. Immediately after a liquidity shock, the spread becomes wider than in the steady state, implying that one dimension of liquidity deteriorates, while at the same time, depth at the best prices increases, meaning an improvement of another liquidity dimension. In subsequent periods, the spread reverts back to the steady-state level but also depth decreases. Also, I find evidence for asymmetries in the impact of shocks on the ask and bid side. Shocks on the ask side have a stronger impact than shocks on the bid side. Finally, resiliency is higher for less-frequently traded stocks and stocks with a larger relative tick size.
