The goal of this paper is to check if different theoretical approaches to price formation can be verified in the structure of empirical input–output tables. From a propositive point of view, the hypothesis is made of two different markets (the ‘industrial’ market of intermediate and investment goods; and the ‘commercial’ market of final consumption goods), with two different mechanisms of price formation. The consequences of this hypothesis are outlined as regards deflation procedures. An empirical test of the theories about price formation and of the method of deflation suggested by the two-market hypothesis is made using 1985 Italian input–output tables at 1980 prices. 相似文献

Summary: Social Policy in the Italian Economy Favourable social and economic conditions constitute the essential framework for a stable development of savings.
Saving in the form of insurance becomes advantageous for the individual, and private insurance can thus extend its activity,
when social attitudes and the economic situation favour the propensity to save.
If conditions change, the State can take over the coverage of risks through social insurance. By means of this institutions,
an anti-cyclical policy can be pursued: the amount of social security contributions, for instance, can be increased during
the expansion of the cycle and the amounts thus accumulated can be used to grant benefits during the recession period, when
contributions can be fixed at a lower percentage of wages.
Another type of policy can be pursued by government authorities: that of adjusting social security contributions to industrial
profits, thereby directing the subsequent effects on economic growth.
Inflation cab cause instability in decisional policies taken by private insurance companies. A solution to the unbalanced
increase of costs can be found in index-linking. Life policies of this kind, for instance, cab be closely related to investments
in houses, to be bought by the insured themselves in price-linked instalments.
After a reference to present developments regarding risk instability and to possibilities of new forms of insurance, this
paper considers the competition resulting from the opening of the EEC insurance markets as an opportunity for the Italian
market to strengthen its structures.

We assess the employment impact of the Lisbon Strategy, examining long-run growth in total, female and old-age employment rates from 1994 to 2009. The Strategy had some impact, especially for old-age workers, but no improvement ensued from its mid-term reassessment. 相似文献

Multinational corporations (MNCs) need to sense, source, and mobilize knowledge when and where it arises, whether at home, or elsewhere in the world. For this reason, MNCs benefit from employee networks of relationships that span across intraorganizational barriers, allowing for the efficient mobilization of knowledge across boundaries. Yet, which organizational members are more likely to be able to develop these boundary spanning networks? We leverage a unique data set from a large multinational corporation to empirically test a comprehensive model that captures the effect of an employee’s mandate, expertise, and behavioral orientations on her likelihood to span intraorganizational boundaries that manifest themselves in the form of hierarchies, intra-functional domains, and geographic territories. We find that the employees that are more likely to be boundary spanners are those having mandates with a global impact, high levels of expertise, and a collaborative orientation in their networking behaviors. In addition, we find that these effects are stronger for those employees that have large formal workflow networks. 相似文献

We investigate the asymptotic and finite sample properties of the most widely used information criteria for co‐integration rank determination in ‘partial’ systems, i.e. in co‐integrated vector autoregressive (VAR) models where a sub‐set of variables of interest is modelled conditional on another sub‐set of variables. The asymptotic properties of the Akaike information criterion (AIC), the Bayesian information criterion (BIC) and the Hannan–Quinn information criterion (HQC) are established, and consistency of BIC and HQC is proved. Notably, the consistency of BIC and HQC is robust to violations of weak exogeneity of the conditioning variables with respect to the co‐integration parameters. More precisely, BIC and HQC recover the true co‐integration rank from the partial system analysis also when the conditional model does not convey all information about the co‐integration parameters. This result opens up interesting possibilities for practitioners who can now determine the co‐integration rank in partial systems without being concerned about the weak exogeneity of the conditioning variables. A Monte Carlo experiment based on a large dimensional data generating process shows that BIC and HQC applied in partial systems perform reasonably well in small samples and comparatively better than ‘traditional’ methods for co‐integration rank determination. We further show the usefulness of our approach and the benefits of the conditional system analysis in two empirical illustrations, both based on the estimation of VAR systems on US quarterly data. Overall, our analysis shows the gains of combining information criteria with partial system analysis. 相似文献

In this paper we study an optimal control problem with mixed constraints related to a multisector linear model with endogenous growth. The main aim is to establish a set of necessary and a set of sufficient conditions which are the basis for studying the qualitative properties of optimal trajectories. The presence of possibly degenerate mixed constraints, the unboundedness and non-strict convexity of the Hamiltonian, make the problem difficult to deal with. We develop first the dynamic programming approach, proving that the value function is a bilateral viscosity solution to the associated Hamilton–Jacobi–Bellman (HJB) equation. Then, using our results, we give a set of sufficient and a set of necessary optimality conditions which involve so-called co-state inclusion: this can be interpreted as the existence of a dual path of prices supporting the optimal path. 相似文献
