Usporedba metoda za procjenu porinuća broda

Porinuće broda složen je događaj, a pogotovo kada su u pitanju netipični brodovi. Iz tog razloga brodogradilišta obavljaju proračune porinuća kako bi odredili brzine i ubrzanja broda, otplov broda, najveći gaz i drugo. Ti su proračuni pouzdani i praktički sva porinuća izvode se uspješno. U ovom radu prikazana je usporedba različitih metoda za procjenu porinuća broda. Tijekom nedavnog porinuća u brodogradilištu Uljanik na brodu su izvedena mjerenja pomoću preciznog diferencijalnog DGPS uređaja (DGPS), a učinjen je i video zapis. Prikupljeni podaci uspoređeni su s podacima proračuna brodogradilišta i teorijskim proračunom. Uočena odstupanja su analizirana i raspravljena

Facilitating trade in intermediate goods: case of EU

A side effect of economic globalisation and new information and communication technologies is the increasing fragmentation of the production process across different countries and continents, contributing to the rise of trade in intermediate goods, which has increased to almost 2/3 of total world trade. Most of this trade, i.e., intermediate goods, are transported by sea. Maritime trade is one of the most economical but also complex ways of trading and transporting goods, requiring good coordination, various stops and controls, transhipments, storage, ICT technology to track the cargo, etc. Therefore, the objective of this paper is to quantify the impact of trade facilitation on trade in intermediate goods on the sample of EU28 countries, using biennial data for the period 2010-2018. We estimate augmented gravity model on bilateral trade data using a Poisson Pseudo Maximum Likelihood (PPML) estimator. Our results suggest that, as expected, logistics, and in particular ICT development, has a significant and positive effect on trade in intermediate inputs, when controlling for other variables in the gravity model such as GDP of trading partners, distance, contiguity, existence of a free trade agreement, exchange rate, and common cultural proxies. Our results support the global trend of development and investment in logistics, and, in particular, new ICT technologies, which can not only contribute to the continued growth of trade in intermediates, but also help mitigate the negative effects of recent global economic shocks

MACROECONOMIC DETERMINANTS OF WINE PRODUCTION IN THE EUROPEAN UNION

This paper focuses on the determinants of wine production in the European wine industry. In the last two decades, the European wine industry has undergone many changes due to the entry of new countries into the world wine market. Although increasing competitiveness became the priority of the European Common Agricultural Policy, wine production and consumption in the EU have decreased in the last two decades, and therefore the aim of this research is to analyse and identify the macroeconomic determinants of wine production, i.e. what factors besides the price influence wine production in selected EU countries and in how they can be controlled. Empirical research was conducted using data for EU member states traditionally engaged in wine production. Panel data on wine production, wine consumption, average wine price, wine imports, wine exports and EU support to the wine sector were collected from secondary sources for 15 wine-producing EU countries and for the period 2009-2018. We estimated the econometric model using pooled OLS, as diagnostic tests indicated that this estimator was the best fit for our data. Our results suggest that domestic demand and domestic (EU) subsidies are the main drivers of wine production. To keep up with New World wine producers, even more emphasis should be placed on promoting the wine drinking culture
