When Aiyagari meets Piketty: Growth, Inequality and Capital Shares
2021
We incorporate the division of income between capital and labor into analysis on the relationship between inequality and growth. Using historical data, we document that changes in the top 1 % income shares are positively associated with subsequent growth of per capita GDP when the capital share of income is low, whereas under high capital share, the association is negative. We show that these findings are compatible with a theoretical analysis that emphasises how changes in the distribution of income translate into the accumulation of capital and overall economic activity through the interplay between precautionary saving motives and consumption smoothing. We also investigate how accounting…
IL TRACCIATO DEL GAS A PALERMO TRA PERMANENZE E VARIAZIONI
2019
La presenza di infrastrutture primarie come luce e gas, all'interno dei centri abitati costituisce un tema di analisi del rapporto tra il sistema dei tracciati e la pianificazione urbana. Alla fine del diciannovesimo secolo, Londra, Parigi e alcune città italiane come Palermo furono dotate di illuminazione artificiale a gas. Nel 1914, per sostenere l'espansione della città verso Nord, fu costruito un nuovo gasometro in posizione centrale rispetto al tracciato urbano di Via Libertà per distribuire il gas ai nuovi quartieri nascenti. Dopo l'arrivo della corrente elettrica il gasometro divenne un luogo abbandonato, ma continuò ad essere custode della memoria di un passato, elemento di riconosc…
Inflation and optimal monetary policy in a model with firm heterogeneity and Bertrand competition
2018
Abstract We study the joint implications of heterogeneity of total factor productivity and strategic price interactions between firms on the dynamics of inflation and the design of optimal monetary policy. In this setting, more productive firms respond less to shocks affecting their marginal costs than less productive firms. As a consequence, economies with a larger proportion of highly productive firms face a flatter Phillips curve. Moreover, when these two features concur, the Ramsey problem gives rise to an optimal non-zero long run inflation that amplifies the differences in relative prices between more efficient and less efficient firms, thus increasing the market share of the former. …
Market Polarization and the Phillips Curve
2021
The Phillips curve has flattened out over the last decades. We develop a model that rationalizes this phenomenon as a result of the observed increase in polarization in many industries, a process along which a few top firms gain an increasing share of their industry market. In the model, firms compete a la Bertrand and there is exit and endogenous market entry, as well as optimal up and downgrading of technology. Firms with larger market shares find optimal to dampen the response of their price changes, thus cushioning the shocks to their marginal costs through endogenous countercyclical markups. Thus, regardless of its causes (technology, competition, barriers to entry, etc.), the recent i…
Using store level scanner data to improve category management decisions: Developing positioning maps
2009
This paper provides evidence of the usefulness of aggregated point-of-sale scanner data to infer the positioning of competing brands, providing valuable information for category management and hence facilitating decision making. Specifically, the authors propose a methodology to study the internal market structure based on market share models with latent heterogeneity when only macro-level time series data (not individual choices) are available. The proposed approach assumes a multidimensional decomposition, latent in the preference structure that is implicit to these types of models. By empirically applying this approach, the authors (1) simultaneously identify both latent dimensions of co…
Is the French mobile phone cartel really a cartel?
2009
International audience; France Telecom (FT), SFR and Bouygues Telecom (BT) have been fined by France's Conseil de la Concurrence (CC) for organizing a mobile phone cartel with stable market shares (one-half, one-third and one-sixth, respectively) and for directly exchanging commercial information. While not contesting the legal decision, it is argued here that the economic reasoning is flawed. (1) As the CC made much of the firms' stable market shares, we have first followed this line of reasoning by considering that the market shares are quotas under uniform costs. Even if there is a general incentive to form a monopolistic cartel, BT was too small for it to be worth its while to join it; it i…
Uzņēmējdarbības procesa izveide SharePoint sadarbības sistēmā
2019
Kvalifikācijas darbs apraksta komercprojektu reģistrācijas sistēmu. Šī sistēma ir paredzēta uzņēmumiem, kas strādā ar Sharepoint vidi. Tas ļauj uzņēmuma darbiniekiem, kuriem ir piekļuve serverim, izveidot un aizpildīt reģistrācijas veidlapu, kas satur informāciju par savu nākotnes projektu vai to rezultātus viegli pieejamā PDF formātā, kā arī iespēju uzņēmuma “galveniem” dot atļauju tās īstenošanai. Sistēmā ir trīs galvenas lietotāju grupas. Katrai lietotāju grupai ir paredzētas noteiktas iespējas izmantot informāciju, kas ir ievadīta PDF veidlapā. Izstrādātās sistēmas mērķis ir automatizēt jaunu projektu reģistrāciju ķīmijas rūpniecībā, kas paātrinās darba procesu un atvieglos komunikāciju…
The Common Good Balance Sheet, an Adequate Tool to Capture Non-Financials?
2019
In relation to organizational performance measurement, there is a growing concern about the creation of value for people, society and the environment. The traditional corporate reporting does not adequately satisfy the information needs of stakeholders for assessing an organization&rsquo
Top Management Team Diversity and Ambidexterity: The Contingent Role of Shared Responsibility and CEO Cognitive Trust
2017
Earlier research has suggested that diversity is a double-edged sword when achieving organizational ambidexterity. While it may contribute to the development of new combinations of exploration and exploitation, it may also lead to disagreements and potential conflict within top management teams (TMTs). To improve our understanding of the effectiveness of diversity in ambidextrous organizations, we develop a synergistic perspective on TMT diversity and examine how two types of diversity – functional and age diversity – affect the achievement of organizational ambidexterity. We also identify shared responsibility and CEO cognitive trust as important contingencies that may complement the effec…
Effects of Raising Minimum Wage: Theory, Evidence and Future Challenges
2013
Abstract Minimum wage is one of the most studied topics in economics. This paper examines some of the most important issues related to the effects of raising minimum wage, based on new contributions in theoretical and empirical research, roughly since 2008. Our purpose was to find in the literature an explanation for the recent raise of minimum wage, in some European Union countries and United States and to identify possible effects of this evolution. Most of the studies point little or no employment response to modest increases in the minimum wage, but we argue there are some other effects to consider.
