This study aims to estimate the determinants of international tourist flows between destinations by using the panel gravity model.

The multi-dimensional panel gravity model was used to analyse tourism originating from 30 different countries to the 14 most-visited countries in the world between 2008 and 2016. Income (i.e. per capita gross domestic product for both the origin and destination countries), distance between countries, various economic indicators and six dummy variables were added to the gravity model as control variables.

The results indicated that tourist arrivals depended mainly on economic factors, i.e. income and trade variables were significant determinants of tourist arrivals. The results also suggested that estimated international tourist flows are a negative function of distance, as is postulated in economic theory.

In recent years, gravity models have been used frequently to analyse international tourism demand and have demonstrated their ability to evaluate the effects of various determinants of international tourism for many countries. The literature includes studies that used a two-dimensional panel gravity model to analyse the determinants of tourism demand to a single country from many different countries. This study differs in terms of specificity; in that, it relied on a three-dimensional panel gravity model that allowed for modelling of multiple destination countries. As a result, more comprehensive and general results relative to the determinants of tourism demand were obtained. In addition, the application of a non-nested three-dimensional panel data model, which has limited use, contributes a new perspective to the econometric literature.

本研究旨在通过采用面板引力模型来估计目的地之间国际旅游流量的决定因素。

多维面板引力模型用于分析2008年至2016年间来自30个不同国家的游客赴世界上前14位旅游目的地国家的旅游情况。收入（即客源国和目的地国家的人均国内生产总值）, 国家之间的距离, 各种经济指标和六个虚拟变量作为控制变量加入到引力模型中。

结果表明, 游客到访主要取决于经济因素, 即收入和贸易变量是游客到访的重要决定因素。结果还表明, 估计的国际旅游流量是距离的负函数。

近年来, 引力模型经常被用来分析国际旅游需求, 并证明了它们能够评估许多国家的各种国际旅游决定因素的影响。文献包括使用二维面板引力模型来分析来自许多不同国家的单个国家的旅游需求的决定因素的研究。该研究的不同之处在于, 它依赖于非嵌套集合模型三维面板引力模型, 允许对多个目的地国家进行建模。因此, 此研究获得了与旅游需求决定因素相关的更全面和广泛的结果。此外, 使用不常运用的非嵌套三维面板数据模型的应用为计量经济学文献提供了新的视角。

Este estudio tiene como objetivo estimar los determinantes de los flujos turísticos internacionales entre destinos mediante el uso del modelo de panel de gravedad.

El modelo de gravedad de panel multidimensional se utilizó para analizar el turismo que se originó en 30 países diferentes a los 14 países más visitados del mundo entre 2008 y 2016.

Los resultados indicaron que las llegadas de turistas dependían principalmente de factores económicos, es decir, las variables de ingresos y comercio fueron determinantes significativos de las llegadas de turistas. Los resultados también sugirieron que los flujos turísticos internacionales estimados son una función negativa de la distancia.

En los últimos años, los modelos de gravedad se han utilizado con frecuencia para analizar la demanda turística internacional y han demostrado su capacidad para evaluar los efectos de varios determinantes del turismo internacional para muchos países. La literatura incluye estudios que utilizaron un modelo de gravedad de panel bidimensional para analizar los determinantes de la demanda turística a un solo país desde muchos países diferentes. Este estudio difiere en términos de especificidad en que se basó en un modelo tridimensional de panel de gravedad que permitió el modelado de múltiples países de destino.

The purpose of this paper is to examine the determinants of foreign direct investment (FDI) flows from some leading developed countries (the USA, Japan, Germany, the Netherlands, the UK and France) into major four Asian economies (China, Korea, India and Singapore).

Using one basic and four augmented versions of gravity model technique, the authors tried to examine the determinants of bilateral FDI flows in four major Asian economies. The study used World Development Indicators, CEPII, KOF and Heritage Foundation data for period 2001–2012.

The results revealed that besides the market size for host and source country, other criteria such as distance, common language and common border also influence foreign investors. Other macroeconomic factors such as inflation rate and real interest rate are among the key factors that attract more FDI. In addition to economic factors, institutional and infrastructural factors such as telecommunication, degree of openness, index of globalisation and index of economic freedom also stimulate the international investors from the developed world to the major Asian countries.

It is altogether possible that only a set of home country specific characteristics or host country specific characteristics does not matter when determining FDI. Most empirical studies using indices such as the index of globalisation and economic freedom are subject to certain methodological limitations such as model selection, parameter heterogeneity, outliers and moral hazard.

More distance between the host and source country would result in less FDI flows due to more managerial and raw material supply chain cost. Similarly, more gross domestic product (GDP) and per capita income (PCI) are leading to more FDI flows into Asian economics. Therefore, major Asian economies should frame their economic policies in such a manner where these counties can strengthen their GDP as well as PCI. Furthermore, above countries should open its economy more and more for better FDI flows as it seems that economic globalisation and economic freedom are major determinants of bilateral FDI flows. The negative impact of inflation and interest rate should be controlled.

From policy perspective, higher scores of economic, social and political globalisation also attract high FDI to the host country. On the same line higher scores in economic freedom mean that less restrictions in terms of economic policies and the policy environment are conducive for free trade and resource transfers. Higher scores in trade freedom, investment freedom and freedom from corruptions also show more developed and conducive policy environment. In the same reasoning higher scores in the composite index of economic freedom which takes information from trade freedom, investment freedom and freedom from corruption and others also encourage flow of FDI in to the host country.

This is the first paper which combines the globalisation index, economic freedom index and distance along with some major macroeconomic variables.

The purpose of this paper is to analyze specifications of the China’s foreign trade policy with Organization of the Petroleum Exporting Countries (OPEC) member countries.

The paper conducts three panel data estimations (fixed effect [FE], random effect [RE] and fully modified ordinary least squares [FMOLS]) based on the gravity model approach for bilateral trade patterns in natural resource and non-natural resource commodities between China and 13 OPEC members over the period of 1998-2014.

The findings reveal that the gravity equation fits the data reasonably well. The existence of long-term relationships between the bilateral trade flows and the main components of gravity model – GDP, income (GDP per capita), the difference in income, exchange rate, the openness level, distance and WTO membership – through the FE, RE and the FMOLS approaches was confirmed. The estimation results show that the trade pattern between China and OPEC member countries relies on the Heckscher–Ohlin theory, thus being explained by difference in factor endowments such as energy resources and technology.

To the best of the authors’ knowledge, this is the first attempt to examine the China’s foreign trade policy with the OPEC member countries through a gravity trade approach.

The purpose of this paper is to analyze and compare the similarities in the foreign trade patterns of China and the other BRICS (Brazil, Russia, India, China and South Africa) members.

Three panel data estimations, namely, fixed effect, random effect and fully modified ordinary least squares, have been conducted in this paper based on the gravitational model of international trade for bilateral trade of each BRICS member with five United Nations (UN) regional groups from 2001 to 2015.

The results revealed that Russia has a dissimilar trade pattern, based on the Heckscher–Ohlin (H-O) framework, with these five regional groups, while the other BRICS members follow the Linder hypothesis. Furthermore, it was found that China has a faster pace of globalization, while the rest of the BRICS members have experienced regionalization rather than globalization. In addition, geographical distance, as a proxy for transportation cost, has a weaker negative effect on the trade patterns of China and India, which makes the trade patterns of BRICS members dissimilar.

To the best of the authors’ knowledge, this paper is the first attempt to examine and compare the BRICS member countries’ foreign trade pattern through a gravity trade approach.

The purpose of this paper is to investigate the factors that affect handicraft export from Vietnam to trading partners in the period 2007–2017, and how those factors influence the export of handicraft products of Vietnam.

The research uses the approach of gravity model based on panel data to evaluate the export of Vietnamese handicraft to 50 main trading partners, covering the period from 2007 to 2017.

The estimated results reveal that Vietnam’s GDP, importer’s GDP, trading partner’s population, Vietnam’s inflation, the economic distance between Vietnam and importer, the openness of Vietnam, importing country’s common language and the issue that both Vietnam and importer are member of APEC are the main factors affecting Vietnamese handicraft export.

This study also has some limitations. It is limited in the data, as some other areas in the world have not been observed and included in the research. In the future, a study with large-scale data of space and time should be conducted, which will certainly give a universal result and fewer errors. However, this paper, in our opinion, provides a significant result and may help the government and policy makers to undertake appropriate measures to improve and promote the export of Vietnamese handicrafts to the world markets.

The research describes the current situation, and it studies factors influencing Vietnam’s handicraft export using the qualitative analysis. The result should be useful for the policy maker and enterprises to promote export activities of Vietnamese handicrafts to international markets.

Handicraft export of Vietnam plays an important part in retaining the culture value and social development as well as encouraging sustainable development for the rural poor within the country.

The past research related to Vietnamese handicraft export almost analyzed the situation to promote export handicrafts. This research is based on the study of factors affecting trade and the gravity model to elaborate and supplement the factors that affect the export of handicraft in accordance with the actual conditions of Vietnam.

This paper aims to investigate the determinants of international bilateral tourism demand in countries of Southern Common Market (specifically, Argentina, Brazil and Uruguay) and Chile.

In this study, an augmented gravity model is used to investigate the determinants of international bilateral tourism demand in countries of Southern Common Market. The novel aspect of the analysis is that three models of tourism are defined, depending on the spatial distribution of tourist arrivals and departures. An intra-regional model, an extra-regional model and a general model are estimated using a dynamic panel data model.

The results indicate that traditional gravity variables are significant in explaining bilateral inbound arrivals, but the characteristics and the behavior of the demand of tourism vary on whether the country belongs to the sub-regional bloc.

The differences found in this paper might have some impacts on the desired design and direction of the touristic policies of each country.

This study analyzes the determinants of international tourism demand through different bilateral relationships, differentiating between intra- and extra-block tourisms.

The purpose of this paper is to find out whether under sanctions, Iran’s trade direction has shifted from Europe (trade policy of de-Europeanization) toward Asia (trade policy of Asianization).

The paper conducts three panel data estimations (FE, RE, and FMOLS) based on the gravity model approach for bilateral trade patterns between Iran-25 EU members and Iran-25 Asian countries over the period 2006-2013.

The empirical evidence indicates a significant negative effect of sanctions on Iran-EU bilateral trade, while it has a positive impact on trade between Iran and the Asian countries. These findings empirically confirmed that the imposition of various sanctions related to the Iran’s nuclear program has pushed the foreign trade policy of this country toward Asianization and away from Europeanization.

To the best of the authors’ knowledge, this paper is the first attempt to examine the Iran’s trade policy changing under the imposition of sanctions related to its nuclear program.

This chapter investigates to what extent private and public European food safety standards affect European imports of a key high-value horticultural product such as green beans from Kenya. First, we estimate the ad valorem tariff equivalents of these nontariff measures (NTMs) for the main European importing countries using an extension of the price-wedge method. Second, we embed these estimated tariff equivalents into a gravity model. We find that the trade effects of these measures during the period 1990–2011 move from being positive in the beginning of the period to being increasingly negative from 1995 until 2003 and then tend to vanish at the end of the period as if Kenyan suppliers have progressively adjusted their trade to these NTMs. We also show that the establishment of the Common Market for Eastern and Southern Africa and the East African Community stimulates that trade with European countries.

Economists have had problems interpreting the gravity model, particularly as applied to migration behaviour. Its physical analogy is unappealing and theories of economic behaviour do not generally give rise to gravity laws. Some years ago Niedercorn and Bechdolt (1969) published a paper in which they provide a derivation of the gravity model using utility theory. Their approach is, however, much more applicable to other flows of human interaction across space, such as travel or communication flows, than it is to migration flows. The major purpose of this paper is to indicate a set of assumptions which might underlie a gravity model of migration and to show that these assumptions are quite severe. One important implication is that we should fully expect any real world migration pattern to deviate from the predictions of a gravity model. Nevertheless, the gravity specification may be a useful starting point in the analysis of migration behaviour, as it imposes restrictions on the formulation of the estimating equations. Thus we may fruitfully study how and why the real world migration patterns diverge from gravity flows.

At the heart of the African Growth and Opportunity Act (AGOA) are substantial trade preferences, which coupled with the Generalised System of Preferences (GSP) grant a wide range of goods produced in qualified African countries duty-free access to the USA. To be AGOA-eligible, countries are assessed annually on their progress in undertaking appropriate economic, institutional and human rights reforms. This paper seeks to cover new grounds by exploring whether exports of apparel to US crowds out EU-15's imports from Africa.

This paper employs the gravity model to gauge trade displacement effects from the EU to the US due to AGOA, and whether the more relaxed special waiver embodied in AGOA's apparel provision causes non-knitted exports to EU-15 to be crowded out. The basic gravity model, which posits that trade between two countries is positively influenced by the economic size and negatively affected by the distance between them, is augmented with other trade inhibiting and trade facilitating variables.

The gravity model provides no evidence of trade displacement but, instead, provides support for the hypothesis of complementarity of African exports to the two key markets. A strong positive impact of the bilateral trade between the US and Africa on the EU–African trade is evident mainly before the phasing out of the Agreement on Textiles and Clothing (ATC). This paper finds that Special Rule beneficiaries' exports to the two markets still complement each other, but for every percentage increase in exports to the USA, there is a less than proportionate increase in exports to EU-15 indicating a higher utilisation of the special waiver. This paper also provides evidence for complementary apparel exports to both LDCs (least developing countries) and non-LDCs, with stronger effects on non-LDCs and the non-knitted sector.

Future work could consider the longer lifespan of AGOA following its latest renewal in 2015. This would allow one to also capture the ongoing changes in EU trade arrangements in particular implementation of Economic Partnership Agreements (EPAs). This new agreement comes with more flexible rules of origin requiring single transformation step instead of the double step. As most African nations are still in the process of adopting EPAs, new research can shed more light on complementary or displacement effects once these agreements are adopted.

Since the main intent of AGOA is to enhance Africa's integration into the global economy by encouraging trade and investment, generate employment and increase productivity and per capita income growth, its impact on Special Rule beneficiaries' exports to the US has been extensively examined. However, the indirect effects of this trade agreement on African exports to other key markets providing similar preferences such as the EU has not been fully explored. This study also covers new grounds by examining whether there has been any apparel trade displacement from the EU to the US, as a result of the Act, over 2001–2016 period right from AGOA's inception.
