Incorporating Discrete Choice Experiments into Policy Decisions: Case of Designing Public Long-Term Care Insurance
Discrete choice experiments (DCEs) have been widely used to elicit preferences in the health economics field but recent reviews found that DCE results are rarely incorporated into health policy decisions. We conjecture that one reason is most health policy practitioners only focus on estimating marginal willingness to pay (MWTP), the measure that is not directly applicable for policy-related questions. We show that when designing a new program, translating preference information into the demand for packages and benefits of alternative schemes (the choices made available) can make the DCE results more policy relevant. This concept is illustrated using data collected to evaluate the benefits of introducing a public long-term care insurance program to a middle-income country, Thailand. We find that preferences are very heterogeneous, implying that no one-size-fits-all solution exists. The estimates from the preferred model are then used to calculate benefits and losses (based on the consumer surplus measure) for plausible implementation scenarios such as different universal schemes, multiple-tier schemes, and schemes in which premium are subsidized for low-income households.
On Covid-19: New Implications of Job Task Requirements and Spouse’s Occupational Sorting
The Covid-19 pandemic has disrupted working life in many ways, the negative consequences of which may be distributed unevenly under lockdown regulations. In this paper, we construct a new set of pandemic-related indices from the Occupational Information Network (O*NET) using factor analysis. The indices capture two key dimensions of job task requirements: (i) the extent to which jobs can be adaptable to work from home; and (ii) the degree of infection risk at workplace. The interaction of these two dimensions help identify which groups of workers are more vulnerable to income losses, and which groups of occupations pose more risk to public health. This information is crucial for both designing appropriate supporting programs and finding a strategy to reopen the economy while controlling the spread of the virus. In our application, we map the indices to the labor force survey of a developing country, Thailand, to analyze these new labor market risks. We document differences in job characteristics across income groups, at both individual and household levels. First, low income individuals tend to work in occupations that require less physical interaction (lower risk of infection) but are less adaptable to work from home (higher risk of income/job loss) than high income people. Second, the positive occupational sorting among low-income couples amplifies these differences at the household level. Consequently, low-income families tend to face a disproportionately larger risk of income/job loss from lockdown measures. In addition, the different exposure to infection and income risks between income groups can play an important role in shaping up the timing and optimal strategies to unlock the economy.
Digital Thailand: Analyzing the Impact of Broadband Connectivity on Firm Productivity
Using a large dataset of almost 100,000 manufacturing establishments in Thailand, this paper studies the impact of broadband internet connectivity on firms’ total factor productivity (TFP). The author finds that, for micro-, small-, and medium-sized enterprises, broadband adoption can raise productivity by 23% to 54%. These results support the government’s policies in building the country’s broadband infrastructure. Although the results reveal substantial benefits of broadband adoption, especially for smaller-sized firms, only about 30% of firms reported adopting broadband or having any types of ICT investments. Perhaps, more could be done to encourage broadband adoptions and private ICT investments for firms of all sizes.
Mutual Fund Participation in IPOs: Thai Evidence
Underwriters and co-managers play an important role in IPOs, but because they often have affiliated mutual funds, concerns about conflicts of interest can arise. On the one hand, they can use this affiliation for the benefit of their asset management business (the information advantage hypothesis); on the other hand, they can use mutual funds under their control to support their IPO clients (the quid pro quo hypothesis). In this article, we find that the behavior of lead underwriter-affiliated funds in Thailand is more consistent with the information advantage hypothesis and co-manager-affiliated funds more consistent with the quid pro quo hypothesis. We also find further evidence of strategic placement of IPO stocks within fund family.
Uncertainty and Economic Activity: Does it Matter for Thailand?
This paper investigates the role of domestic and foreign uncertainty shocks for macroeconomic dynamics in Thailand. We construct and compare various indicators of economic and policy uncertainty, including macroeconomic and financial uncertainty, as well as monetary policy, fiscal policy, and political uncertainty. We find that while all uncertainty measures display countercyclical behavior, they generate heterogenous effects on real GDP and its components depending on the type of shock. In general, the magnitude of real activity decline in response to economic and policy uncertainty shocks are on the scale of 1-2 percent, with most of the transmission occurring through investment and trade flows rather than consumption demand. In terms of persistence, Thai macroeconomic uncertainty shocks generate sudden impacts, while the effect of other shocks on the economy are more gradual. Despite being a small open economy, we find that domestic uncertainty shocks can be as prominent as uncertainty shocks that spillover from abroad. Thai monetary policy shocks generate declines in real activity that are as large and persistent as US financial uncertainty shocks, whereas the impact of both Thai fiscal policy uncertainty and US economic policy are both rather short-lived. Furthermore, we find that uncertainty is a key driver of fluctuations in domestic output, with certain types of uncertainty being able to explain up to 40 percent of the variation in real activity, even in the long run. Finally, we observe asymmetry in the effects of downside versus upside economic uncertainty shocks, but no difference between uncertainty of short versus long horizons.
ESG and Creditworthiness: Two Contrary Evidence from Major Asian Markets
Assets managed under sustainable investment criteria have been massively growing during the recent years. Among the criteria, environmental, social and governance (ESG) score leads the group as an important indicator of non-financial quality of a firm, which may reflect value to investors either through higher expected profit or lower risk. In this paper, we focus on the latter by exploring whether ESG score has any impact on the credit rating of firms due to the risk mitigation effect. Ordered logistic regressions were applied on a panel dataset of listed companies in Shanghai and Tokyo Stock Exchanges over 2009 – 2018. The results suggest that only in Japan, having ESG coverage is greatly associated with being awarded higher credit rating. However, just the environmental and governance pillars positively affect the Japanese firms’ credit ratings, while the social pillar shows negative effect.
COVID-19 and Endogenous Public Avoidance: Insights from an Economic Model
In this paper, I study the transmission of COVID-19 in the dynamic SEIR (Susceptible, Exposed, Infectious, and Removed) model that allows individuals to optimally choose their public avoidance actions in response to the COVID-19 risk. I allow for heterogeneity in infection rates across age groups and structurally estimate the parameters to match the daily pattern of new cases and the ratio of patients by age group. Even in the absence of intervention, the elderly,
who face a greater risk of death from COVID-19, are more likely than the young to take self-protective actions. In contrast to models with a fixed transmission rate, my model can capture the heterogeneity in the fraction of infected individuals among different age groups.
Assessing Tax Burden Differential Between Foreign Multinationals and Local Firms: Implications for FDI Tax Incentives
This study uses firm-level data from ASEAN5 to examine whether there are systemic differences in how reported profit is taxed between foreign multinational and comparable local firms. Using propensity score matching, it finds that the effective tax rate (ETR: tax expense divided by pre-tax profit) of foreign MNEs is 1.8 percentage point lower than that of local firms. It also shows that the preferential tax treatment is responsible for 95% of the ETR differential. Under the baseline scenario, the associated revenue loss is 2.6% of total corporate income revenue.
Tax Rate Cut and Firm Investment: Evidence from Thailand
How do firms’ investment respond to a large corporate tax rate cut in developing countries? This study uses a matched difference-in-difference approach to estimate the investment responses of Thailand’s 2012-13 corporate income tax cut. It finds that the tax cut has significantly boosted investment. The findings also underline the heterogeneity of the investment responses between local and foreign firms as well as the potential roles of policy uncertainty and market competition on investment response.
Does Democracy Affect Cyclical Fiscal Policy? Evidence From Developing Countries
Macroeconomics usually prescribes counter-cyclical fiscal policies to stabilise the economy: government spending should increase above trend in the economic downturns, and decrease below trend during booms. Yet, empirical research has documented pro-cyclical fiscal policy in several democratic developing countries. This article uses updated data to analyse 63 developing countries from 1980 to 2013 and robustly shows that pro-cyclical fiscal policy does exist in both democratic and non-democratic developing countries. The essence of this paper is controlling endogeneity issue by the instrumental variable method and investigating the interaction between democracy, its maturity and quality of institutions in affecting fiscal policy cyclical.We provide 3 main findings. Firstly, an improvement in the level of institutions quality plays an important role to restrain pro-cyclical fiscal policy and these effects are larger in democratic countries than non-democratic ones. Additionally, more mature and stable democratic countries tend to implement less pro-cyclical fiscal policy.
Profitability, Investment and Asset Pricing: Reconciling the Valuation and the q-Theory Approaches in the Thai Stock Market
There are several ways to motivate why profitability and investment should affect stock returns. In this paper, I investigate the valuation approach of Fama and French (2015) and the q-theory approach of Hou, Xue and Zhang (2015). While the underlying theories are different, their empirical predictions are the same. Slight differences in factor construction methods afford an opportunity to combine the features of the two models. I find that reinterpreting the q factors (with more frequent rebalancing and more layers of sorting) as Fama-French valuation factors can lead to improvement in model performance. In this modified version, the market risk, size, value, profitability and investment effects are all priced in Thailand.
Reshaping Thailand’s Labor Market Structure: The Unified Forces of Technology and Trade
Improvements in technology can have substantial impact on the labor market both directly and indirectly via changes in global trade patterns. This paper studies the potential impact of computerization and reshoring/relocating of operations by firms on Thailand’s labor market. Specifically, the analysis is built upon Frey and Osborne’s (2017) approach and incorporates additional measures of trade-base tasks. This is so that the revised machine-learning model can account for both the impact of technology and change in global trade patterns. Our results revealed that occupations that are mostly affected are service and sales workers, and agricultural and fishery workers. In the worst-case scenario, approximately one-third of existing jobs (12.14 million jobs) could be at risk. However, in real situations, new types of jobs may be created, workers may voluntarily adjust, or other factors could drive some overseas operations back to Thailand. Therefore, the potential outlook for Thailand’s labor market may not be as severe as the model has predicted.
Farms, Farmers and Farming: A Perspective through Data and Behavioral Insights
This paper aims to contribute to a better understanding of Thai agriculture, the sector that currently employs about one third of the country’s labor force. We first draw out key stylized facts on our farms, farmers and farming from various granular farmer’s administrative data sets that allow us to observe what has happened at the plot, labor and household levels over the past decade, and cover more than 90% of farmers nationwide. We then use a stochastic frontier analysis to identify key drivers of household’s agricultural productivity, and project the potential productivity impacts from the four key driving factors: climate change, aging, irrigation and technology for every tambon nationwide. A meta-analysis is then used to illustrate the landscape of technological development throughout the rice value chain in Thailand. Finally, we use lab in the field experiments to understand behavioral insights that underly farmer’s incentives particularly in the context of technological adoption. Our results shed some lights on how to design, prioritize and implement policies to ensure that our farmers stay competitive, resilient and sustainable.
Words Matter: Effects of Semantic Similarity of Monetary Policy Committee’s Decision on Financial Market Volatility
The objective of the paper is to study the effects of semantic similarity of the Bank of Thailand’s press releases on volatility of financial markets in Thailand from 2010-2018. The Natural Language Processing (NLP) is employed to construct the semantic similarity from 72 press releases. The semantic similarity represents the public signal that the central bank delivers to the public in the framework of a Keynesian beauty contest game.
The semantic similarity of MPC press releases significantly reduce the volatility in 1-month, 3-month, 10-year and 15-year government debt securities. Findings imply that relatively similar language in the MPC press releases reduces the volatility in short-term and long-term bonds. Effects of semantic similarity matter most in the volatility of 10-year bond yield. However, effects of semantic similarity are insignificant in both equity and foreign exchange markets.
Gaining from Digital Disruption: the Thai Financial Landscape in the Digital Era
This paper examines competitiveness of the Thai financial sector through the dimensions of depth, access, efficiency, and stability, as compared to peers. The paper finds that while the Thai financial sector compares reasonably well with peers in most dimensions, it does not fare well in term of SME access to bank credit. Using Panzar-Rosse H-Statistic, the paper also examines competition in the Thai banking sector and finds that the level of competition in the Thai banking sector is consistently high over the sample period. The results raise the question: Why does SME access to bank credit remain low, despite high level of competition in the banking sector? This puzzle is important since SMEs are a key driver of the Thai economy. Reviewing results from various studies and interviews with SMEs and bank credit officers, the paper identifies several bottlenecks in the SME lending process that may lead to market failures. Using data from 1.29 million individual SME loan contracts obtained from 15 Thai commercial banks, and six Specialized Financial Institutions (SFIs), the paper finds that only a few banks attempt to penetrate SMEs at the lower tiers of loan size and income. Although SME lending by SFIs are found to be a good complement to SME lending by banks, the fact remains that fewer than half of SMEs in Thailand have loans from these financial institutions. The paper then discusses how several initiatives have been attempted to harness the power of technology and data to help improve SME access to finance, whether from traditional banks or other types of players. Lessons from the case of SME financing and from other segments of financial sectors in selected countries are then drawn into common themes that might help guide the design of financial landscape in the digital era.
