Industry Dynamics and the Distribution of Firm Sizes: A Non-Parametric Approach

The aim of this paper is to analyze the evolution of the size distribution of young firms within some selected industries, trying to assess the empirical implications of different models of industry dynamics: the model of passive learning (Jovanovic 1982), the model of active learning (Ericson and Pakes, 1995), and the evolutionary model (Audretsch, 1995). We use a non-parametric technique, the Kernel density estimator, applied to a data set from the Italian National Institute for Social Security (INPS), consisting in 12 cohorts of new manufacturing firms followed for 6 years. Since the patterns of convergence to the limit distribution are different between industries, we conclude that the model of passive learning is consistent with some of them, the active exploration model with others, the evolutionary model with all of them.Cohorts; Gibrats Law; Kernel; Industry Dynamics; Non-parametric; Shakeouts.

Entry decisions and adverse selection: an empirical analysis of a local credit markets

During the last decades there has been a widespread relaxation of legal entry barriers into the banking industry, with potential benefits for financial integration and competition. Obstacles to banks' geographical and business expansion have been removed and branching has been substantially liberalized. This paper analyzes the determinants of entry decisions into local credit markets using a unique data set before and after deregulation of the Italian banking industry. We estimate an entry model à la Poisson and find evidence that spreads between loan and deposit rates drive entry only for newly chartered banks, but does not affect the decision to open branches of banks operating in other markets. Branching by outside banks is instead positively correlated with business opportunities in the provision of financial services which do not require the acquisition of substantial proprietary information. Both these results are consistent with the hypothesis that in credit markets incumbents have an informational advantage over new entrants.Entry, deregulation, informational barriers, count data, overdispersion

Revisiting the empirical evidence on firmsÂ’ money demand

In this paper we estimate the demand for liquidity by US non financial firms using data from COMPUSTAT database. In contrast to the previous literature, we consider firm-specific effects, such as cost-of-capital and wages. From the balanced and unbalanced panel estimations we infer that there are economies of scale in money demand by US business firms, because estimated sales elasticities are smaller than unity. In particular, they are lower than in previous empirical studies, suggesting that economies of scale in the demand for money are even bigger than formerly thought. In addition, it emerges that labor is not a substitute for money.Panel Data, Liquidity, Demand for Money, COMPUSTAT

The Costs and Benefits of Informality

We explore the costs and benefits of informality associated with the informal sector lying outside the tax regime in a two-sector New Keynesian model. The informal sector is more labour intensive, has a lower labour productivity, is untaxed and has a classical labour market. The formal sector bears all the taxation costs, produces all the government services and capital goods, and wages are determined by a real wage norm. We identify two welfare costs of informalization: (1) long-term costs restricting taxes to the formal sector and (2) short-term fluctuation costs of tax changes to finance fluctuations in government spending. The benefit of informality derives from its wage flexibility. We investigate whether taxing the informal sector and thereby reducing its size sees a net welfare improvement.Informal economy, labour market, tax policy, interest rate rules

Labour Market and Investment Effects of Remittances

This paper examines the relationship between remittances from interna- tional migration and imperfections in labour and capital markets. We use a search-matching model of the labour market to show that remittances can have two opposing effects on the labour market of the source country. First, they raise the utility of the unemployed members back home and, if a worker's bargaining power is low, this causes the unemployment rate to rise. Second, remittances available for investment will relax credit constraints encountered by firms. If the `investment effect' outweighs the `search income' effect, then remittances will reduce the unemployment rate. Our empirical analysis sug- gests that remittances have a small negative effect on unemployment, but a positive and significant effect on investment.migration, remittances, capital constraints.

The Post-entry Size Adjustment of New small Firms

The hypothesis underlined in this paper is that apart from infant mortality there is another relevant phenomenon taking place within new-born Small Business Enterprises (SBEs) in the period immediately after entry; namely that the smaller ones among them, having entered with a marked sub-optimal scale,adjust their size towards the mean size exhibited by larger SBEs. In the paper this hypothesis is tested using a cohort of 1,570 new firms, and applying a Gibrat-like specification with sample selection. The hypothesis of a size adjustment by smaller new entrants immediately after entry is confirmed in most selected industries in Italian manufacturing; more specifically, surviving smaller new SBEs show higher rates of growth in the first year (in one case in the first two) immediately after start-up, while they converge towards the average rate of growth of the whole cohort of new SBEs in the following years.-
