Effective strategies for internal outsourcing and offshoring of business services: An empirical investigation

The growing pressure to reduce costs and improve efficiency induces many organizations to undertake shared services initiatives. This consolidation and streamlining of common business functions is also known as insourcing, in-house services, business services, or staff services. While adoption of a shared service structure is viewed by many as an appropriate strategy to pursue, most companies still struggle to devise optimal strategies and to generate adequate returns on investments for their projects, because none of the approaches that are commonly adopted is recognized as universally effective.     

The macrodynamics of financial fragility within a hard peg arrangement

The paper presents an open-economy macrodynamical growth model with the aim of giving an endogenous characterisation to the process that leads a small country with a currency-board arrangement to accumulate dangerously high levels of external debt and become vulnerable to macroeconomic instability. The macrodynamics of the model results from the combination of the commitment to maintain the peg - that makes liquidity closely dependent on the dynamics of foreign reserves - and the non-linear real and financial interactions that drives the pro-cyclical behaviour of the economy. Within this context, the external financing ease during an economic upswing leads to debt-supported growth and financial fragility; the consequent deterioration of profitability expectations brings about a capital reversal that, in the absence of monetary stabilisation tools, makes the currency arrangement unsustainable. A financial crisis may thus turn into a currency crisis.We run a continuous-time estimation of a non-linear differential equations system for Argentina during the years of the currency-board arrangement. We find that two steady-state solutions exist. The local stability and sensitivity analysis show that both equilibria are unstable and that the qualitative nature of the equilibria depends in particular on lenders' responsiveness to the degree of leverage. We also show that relaxing the assumption on the currency arrangement and allowing for an autonomous monetary policy makes both equilibria stable.     

Unobserved Heterogeneity or Measurement Errors? Testing for Correlated Effects with Measurement Errors *

This paper addresses the problem of endogenous regressors due to the presence of unobserved heterogeneity, when this is correlated with the regressors, and caused by regressors’ measurement errors. A simple two‐stage testing procedure is proposed for the identification of the underlying cause of correlation between regressors and the error term. The statistical performance of the resulting sequential test is assessed using simulated data.     

The strength of weak ties in crime

The aim of this paper is to investigate whether weak ties play an important role in explaining criminal activities. We first develop a model where individuals learn about crime opportunities by interacting with other peers. These interactions can take the form of either strong or weak ties. We find that increasing the percentage of weak ties induces more transitions from non-crime to crime and thus the crime rate in the economy increases. This is because, when the percentage of weak ties is high, delinquents and non-delinquents are in close contact with each other. We then test these predictions using the U.S. National Longitudinal Survey of Adolescent Health (AddHealth), which contains unique detailed informations on friendship relationships among teenagers. The theoretical predictions of our model are confirmed by the empirical analysis since we find that weak ties, as measured by friends of friends, have a positive impact on criminal activities.     

Environmental Strategies,Upgrading and Competitive Advantage in Global Value Chains

The literature is increasingly focusing on how firms are improving their environmental performances and promoting green strategies to transform environmental constraints into new drivers of competitive advantage. This paper contributes to the literature by expanding knowledge about environmental management at the value chain level by exploring the concept of environmental upgrading and its implications in terms of economic upgrading and greening of industries. Leveraging on the global value chain and environmental managerial literature, the paper develops an integrated theoretical framework to analyse environmental upgrading trajectories and their implications in terms of firms' green strategies based on case studies in the Italian home‐furnishing industry. Empirical evidence suggests that firms develop green strategies to reduce environmental impacts while achieving economic benefits and competitiveness, which may be internal to the firm but also apply to value chains, with different implications in terms of bargaining power and value appropriation.

Spatial determinants of productivity: Analysis for the regions of Great Britain

This paper uses NUTS3 sub-regional data for Great Britain to analyse the determinants of spatial variations in income and productivity. We decompose the spatial variation of earnings into a productivity effect and an occupational composition effect. For the former (but not the latter) we find a robust relationship with proximity to economic mass, suggesting that doubling the population of working age proximate to an area is associated with a 3.5% increase in productivity in the area. We measure proximity by travel time, and show that effects decline steeply with time, ceasing to be important beyond approximately 80 min.     

The Short Period and the Long Period in Macroeconomics: An Awkward Distinction

The aim of this paper is to show that the meaning of the well-known concepts of short period and long period is often unclear and may be seriously misleading when applied to macroeconomic analysis. Evidence of this confusion emerges through reappraisal of the interpretative debate of the 1980s and 1990s, which aimed to establish whether Keynes's General Theory should be considered a short- or long-period analysis of the aggregate level of production. Further evidence is provided by the ambiguous use that seems to be made of this distinction in macroeconomics textbooks, as will be shown in the paper. Having explored some possible explanations for the difficulties in defining and applying these methodological tools at a ‘macro’ level, the conclusion is drawn that it would be preferable to abandon this terminology in classifying different aggregate models and simply to make explicit the given factors and the independent and dependent variables in each model, exactly as Keynes did in Chapter 18 of his major work.
