Abstract:
In the era of big data, economists are exploring new data sources and methodologies to improve economic forecasting. This study examines the potential of big data and machine learning in enhancing the predictive power of international macroeconomic forecasting models. The research utilizes both structured and unstructured data to forecast Korea's GDP growth rate. For structured data, around 200 macroeconomic and financial indicators from Korea and the U.S. were used with machine learning techniques (Random Forest, XGBoost, LSTM) and ensemble models. Results show that machine learning generally outperforms traditional econometric models, particularly for one-quarter-ahead forecasts, although performance varies by country and period. For unstructured data, the study uses Naver search data as a proxy for public sentiment. Using Dynamic Model Averaging and Selection (DMA and DMS) techniques, it incorporates eight Naver search indices alongside traditional macroeconomic variables. The findings suggest that online search data improves predictive power, especially in capturing economic turning points. The study also compares these big data-driven models with a Dynamic Stochastic General Equilibrium (DSGE) model. While DSGE offers policy analysis capabilities, its in-sample forecasts make direct comparison difficult. However, DMA and DMS models using search indices seem to better capture the GDP plunge in 2020. Based on the research findings, the author offers several suggestions to maximize the potential of big data. He stresses the importance of discovering and constructing diverse data sources, while also developing new analytical techniques such as machine learning. Furthermore, he suggests that big data models can be used as auxiliary indicators to complement existing forecasting models, and proposes that combining structural models with big data methodologies could create synergistic effects. Lastly, by using text mining on various online sources to build comprehensive databases, we can secure richer and more real-time economic data. These suggestions demonstrate the significant potential of big data in improving the accuracy of international macroeconomic forecasting, particularly emphasizing its effectiveness in situations where the economy is undergoing rapid changes.

Abstract:
The African continent is confronting the prospect of a new debt crisis. The COVID-19 pandemic wreaked havoc on government finances. The Russian government’s war against Ukraine has increased the cost of food and energy, and compelled investors to sell off government bonds in emerging markets. Rising interest rates in the United States will increase the cost of borrowing. The Chinese economy is struggling under the weight of Xi Jinping’s “Zero COVID” policy and accumulated real estate debt. In 2015, the International Monetary Fund announced that eight countries were in debt distress. By March 2022, 23 were. In June, public debt ratios reached a 20-year high. Africa’s debt-distressed governments “are unlikely to default” in 2022,” The Economist observed, “but face trouble by 2024.” There is some evidence that the debt crisis is especially acute for Africa’s non-democracies. The impending debt crisis coincides with a general sense that Africa is experiencing a democratic recession. Voters are increasingly subject to intimidation and violence. Incumbent presidents are removing term limits. The longstanding norm against military coups is fading.

3. China: Rise or Demise?

Abstract:
China, even if it rises, does not present much of a security threat to the United States. Policymakers increasingly view China’s rapidly growing wealth as a threat. China currently ranks second, or perhaps even first, in the world in gross domestic product (although 78th in per capita GDP), and the fear is that China will acquire military prowess commensurate with its wealth and feel impelled to carry out undesirable military adventures. However, even if it continues to rise, China does not present much of a security threat to the United States. China does not harbor Hitler‐​style ambitions of extensive conquest, and the Chinese government depends on the world economy for development and the consequent acquiescence of the Chinese people. Armed conflict would be extremely—even overwhelmingly—costly to the country and, in particular, to the regime in charge. Indeed, there is a danger of making China into a threat by treating it as such and by engaging in so‐​called balancing efforts against it. Rather than rising to anything that could be conceived to be “dominance,” China could decline into substantial economic stagnation. It faces many problems, including endemic (and perhaps intractable) corruption, environmental devastation, slowing growth, a rapidly aging population, enormous overproduction, increasing debt, and restive minorities in its west and in Hong Kong. At a time when it should be liberalizing its economy, Xi Jinping’s China increasingly restricts speech and privileges control by the antiquated and kleptocratic Communist Party over economic growth. And entrenched elites are well placed to block reform. That said, China’s standard of living is now the highest in its history, and it’s very easy to envision conditions that are a great deal worse than life under a stable, if increasingly authoritarian, kleptocracy. As a result, the Chinese people may be willing to ride with, and ride out, economic stagnation should that come about—although this might be accompanied by increasing dismay and disgruntlement. In either case—rise or demise—there is little the United States or other countries can or should do to affect China’s economically foolish authoritarian drive except to issue declarations of disapproval and to deal more warily. As former ambassador Chas Freeman puts it, “There is no military answer to a grand strategy built on a non‐​violent expansion of commerce and navigation.” And Chinese leaders have plenty of problems to consume their attention. They scarcely need war or foreign military adventurism to enhance the mix. The problem is not so much that China is a threat but that it is deeply insecure. Policies of threat, balance, sanction, boycott, and critique are more likely to reinforce that condition than change it. The alternative is to wait, and to profit from China’s economic size to the degree possible, until someday China feels secure enough to reform itself.

Abstract:
The relationship among the FDI, GDP and Export has gained vast attention among the researchers and policy-makers. There are many studies on the interaction of these variables using various econometric approaches in the literature. However, it has seen that the findings have been different from country by country. Therefore, this study's main problematic is to estimate the coefficients that show the interaction among the FDI, GDP and Export covering 1980-2019 in Turkey. The ARDL Bounds Model and Granger Causality approach were selected to measure the coefficients statistically. Three models were executed to calculate the short-run and long-run coefficients. While the Model 1 and Model 3 were found statistically significant to explain the dependent variables, the Model 2 was found statistically insignificant. Because of this, the Model 2 was excluded from the study. The short- run coefficients were also found statistically significant to explain the dependent variables of the Model 1 and Model 3. While GDP affects the FDI positively in Model 1, GDP affects the Export negatively in Model 2. The ECT was found statistically significant at 0.01. The speeds of adjustment of the Model 1 and Model 3 were calculated as approximately 93% and 16% levels, respectively. Unlike the ARDL Bounds Model, the Granger Causality test was implemented to measure the variables' causal relationship. It was seen that there is only a unidirectional Granger causal relationship running from GDP to FDI in the Model 1 and from GDP to Export in the Model 2.

Abstract:
A timely and reliable prediction of economic activities is crucial in policymaking, especially in the current COVID-19 pandemic situation, which requires real-time decisions. However, making frequent predictions is challenging due to the substantial delays in releasing aggregate economic data. This study aims to nowcast Indonesia’s economic activities during the COVID-19 pandemic using the novel high-frequency Facebook Mobility Index as a predictor. Employing mixed-frequency, mixed-data sampling, and benchmark least-squares models, we expanded the mobility index and used it to track the growth dynamics of the gross regional domestic product of provinces in Java and Bali and performed a bottom-up approach to estimate the aggregated economic growth of the provinces altogether. Our results suggested that the daily Facebook Mobility Index was a considerably reliable predictor for projecting economic activities on time. All models almost consistently produced reliable directional predictions. Notably, we found the mixed data sampling-autoregressive model to be slightly superior to the other models in terms of overall precision and directional predictive accuracy across observations.

Abstract:
Elderly populations in Asia are expanding more quickly than other age groups. This shift in population age structure had two major impacts: demand for income support for the elderly will rise because their labor income tends to be extremely low; and gross domestic product (GDP) and other aggregate economic indicators will grow more slowly as growth in the effective labor force declines. In countries where government programs play an important role in old-age support, tax rates will have to rise or benefits will have to be curtailed or both—all options with significant political costs.

7. A stagnant China in 2040, briefly

Abstract:
There is a considerable chance China will stagnate by 2040, with gross domestic product growth at 1–1.5 percent. The process has started, seen most clearly in stark trends for debt and aging, but better-quality data on productivity would clarify how far along stagnation is and whether it at some point reverses. China shows no sign of adopting pro-productivity reform. It will not spur growth by leveraging or bolster a shrinking labor force through current population and education policy. Innovation will help, but a large economy requires broad innovation, and the party dislikes competition. A twist comes from China’s global position, which will not deteriorate much. Outbound investment has retrenched, and the yuan’s rise was exaggerated. Consumption exports and commodities imports will stall. But China will easily be a top-two market in most sectors, and other countries are not acting to displace it. Instead, localization will occur. Commodities producers and some developing countries will lose, the latter as Chinese capital dries up. Countries that make difficult reforms will win. Consumer goods will see inflation, but innovation will be healthier with less Chinese influence. American firms will seek new pastures, and Chinese stagnation means production may relocate to the US.

8. Supply-side reform leads to economic resilience

Policy Brief
Abstract:
China's GDP grew 6.6 percent in 2018, according to National Bureau o ftatistics data. Despite the slight slowdown in the GDP growth rate, however, exports grew at a relatively high 9.9 percent year-on-year calculated in US dollars. And, not surprisingly, China's trade surplus with the United States expanded further. ...... Besides, the relative prosperity index of small and medium-sized enterprises has dropped to the second-lowest point in a decade, and the financial cost differentiation among various industries is growing. This may have a negative impact on not only short-term macroeconomic stability, but also the development space of relevant emerging industries and long-term growth momentum.

Center for the Advanced Study of India
Abstract:
Following an overwhelming election victory, Prime Minister Narendra Modi’s new government has a golden opportunity to bring about historic reforms in the agricultural sector to improve farmer livelihoods and national food security. The sector affects the economic well-being of half the Indian population and the access to affordable and nutritious food for all Indians. Fundamental reforms can achieve sustainable and broadly distributed agricultural growth that will add to India’s GDP, increase export earnings, help conserve increasingly scarce resources of land and water, and enable the more orderly movement out of agriculture and into other productive sectors. Reforms in four areas should be the priority if Prime Minister Modi’s bold goal of doubling farmer incomes is to be accomplished in the coming years. First, the focus of agricultural policies must shift from production per se to farmers’ livelihoods. Second, policies to improve the allocation and efficiency of land and water are essential if the critical resources of water and land are to be conserved. Third, reforms are needed to help farmers cope with the growing risks of weather and price volatility. Fourth, agricultural markets must be opened to greater competition and provided with better infrastructure if farmers are to realize better returns for produce while ensuring nutritional security for low-income consumers. Agriculture is a state subject but where the Central government has had—and will continue to have—a large role. Reforms can only succeed if the Central and state governments work closely together in a spirit of “cooperative federalism.” Many of the important levers of change—water, power, irrigation, extension, agri-markets, etc.—are controlled by the states. Going forward, it would be helpful if the government created an Agri-Reforms Council on the lines of GST Council for a somewhat longer term than is currently done (for two months). The focus for the Government of India will need to be twofold: actions that it can unilaterally take to raise agricultural incomes; and second, actions to influence state government efforts to improve agriculture with its sustainability at the core. The steps listed should be thought of as a package, which will have an impact if most are implemented and not one or two in isolation.  Reduce cereal procurement and keep MSP price increases for rice and wheat below inflation, and not exceeding border prices, while encouraging the private sector to develop robust markets in less water intensive crops like pulses and oilseeds by removing controls on stocking, trading, exports, etc. This will also have a beneficial impact on depleting water tables in certain regions, notably in north-west and southern India.  Implement income transfers scheme for farmers in tandem with reductions in the subsidies for power, water, and fertilizer that distort incentives and hinder change. This will have large positive environmental effects and help toward better natural resource management. Keep the real prices of subsidized grains under the National Food Security Act, 2013 and link them to the MSP to incentivize the production and consumption of non-cereals.  Scrap the Essential Commodities Act and other laws designed fifty years ago for conditions of scarcity. Those conditions of scarcity have long since disappeared. India is trying to cope more with the problems of surfeit than scarcity.  Focus on income from livestock to help marginal farmers (<1 ha). Change laws and more importantly the political and social climate that have been so detrimental to the livestock sector lately.  Eliminate or reduce dramatically export restrictions and export taxes on agricultural products. Trade policies that have been arbitrarily and pro-cyclically imposed (increasing tariffs and import restrictions when world prices come down, and imposing export bans and taxes when domestic prices rise)—must become stable and predictable by setting “trigger levels” well in advance.  Accelerate the effort to create a single agricultural market by introducing assaying, grading, setting standards, bringing “Uber-type” logistical players on e-platforms to move goods from one region to another, and setting dispute settlement mechanisms so that farmers and farm organizations can transact with any buyer, anywhere in India, and at any time of their choosing.  Support the creation of public mandis as a viable alternative to private trade. Most importantly, across the board, increase marketing options available to farmers while subsidizing market infrastructure improvements.  End support for the rehabilitation of inefficient urea plants and create a plan for closing the most inefficient plants.  Incentivize the passing of state laws to allow easy leasing/renting of agricultural land and relax restrictions on conversion of agricultural land for other purposes. At present, these restrictions keep the value of agricultural land low and raise the barriers to exit from agriculture. Finally, even as these reforms are undertaken, it needs to be recognized that growth and employment opportunities outside agriculture are critical for long-term improvements in farmers’ incomes. Relentless population pressures have meant that most Indian farms are too small to provide viable incomes. The long-term future of Indian farmers fundamentally depends on getting many people out of farming. Ironically, that future will come about more reliably if policies to improve agricultural production and incomes are pursued today.

10. Redefining Liquidity for Monetary Policy

Korea Institute for International Economic Policy (KIEP)
Abstract:
This paper proposes a monetary aggregate “Liquidity” that could serve as a useful indicator for gauging the appropriateness of monetary policy. If liquidity rises above a certain threshold, it is signaling that monetary policy is losing traction due to structural and other impediments even when the inflation gap remains open. This indicator supplements the financial cycle approach but adds value by providing a benchmark that is derived from the national account, and not based on its own trend. Over the last two decades, each time this measure rose above the threshold range, it was followed by a decline in GDP growth. The latter was greater when accompanied by a high physical asset value to GDP, e.g., an elevated property market.
